-         0.8.11<p>
-Enables or disables the use of asynchronous file I/O (AIO)
-on FreeBSD and Linux.
-</p><p>
-On FreeBSD, AIO is usable starting from FreeBSD 4.3.
-AIO can either be linked statically into a kernel:
-<blockquote><pre>
-options VFS_AIO
-</pre></blockquote>
-or loaded dynamically as a kernel loadable module:
-<blockquote><pre>
-kldload aio
-</pre></blockquote></p><p>
-In FreeBSD versions 5 and 6, enabling AIO statically, or dynamically
-when booting the kernel, will cause the entire networking subsystem
-to use the Giant lock that can impact overall performance negatively.
-This limitation has been removed in FreeBSD 6.4-STABLE in 2009, and in
-FreeBSD 7.
-However, starting from FreeBSD 5.3 it is possible to enable AIO
-without the penalty of running the networking subsystem under a
-Giant lock - for this to work, the AIO module needs to be loaded
-after the kernel has booted.
-In this case, the following message will appear in
-<code>/var/log/messages</code><blockquote><pre>
-WARNING: Network stack Giant-free, but aio requires Giant.
-Consider adding 'options NET_WITH_GIANT' or setting debug.mpsafenet=0
-</pre></blockquote>
-and can safely be ignored.
-
-The requirement to use the Giant lock with AIO is related to the
-fact that FreeBSD supports asynchronous calls
-<code>aio_read()</code>
-and
-<code>aio_write()</code>
-when working with sockets.
-However, since nginx only uses AIO for disk I/O, no problems should arise.
-</p><p>
-For AIO to work,
-<a href="#sendfile">sendfile</a>
-needs to be disabled:
-<blockquote><pre>
-location /video/ {
-    sendfile       off;
-    aio            on;
-    output_buffers 1 64k;
-}
-</pre></blockquote></p><p>
-In addition, starting from FreeBSD 5.2.1 and nginx 0.8.12, AIO can
-also be used to pre-load data for <code>sendfile()</code>:
-<blockquote><pre>
-location /video/ {
-    sendfile       on;
-    tcp_nopush     on;
-    aio            sendfile;
-}
-</pre></blockquote>
-In this configuration, <code>sendfile()</code> is called with
-the <code>SF_NODISKIO</code> flag which causes it not to
-block on disk I/O and instead report back when the data are not in
-memory; nginx then initiates an asynchronous data load by reading
-one byte. The FreeBSD kernel then loads the first 128K bytes
-of a file into memory, however next reads will only load data
-in 16K chunks. This can be tuned using the
-<a href="#read_ahead">read_ahead</a>
-directive.
-</p><p>
-On Linux, AIO is usable starting from kernel version 2.6.22;
-plus, it is also necessary to enable
-<a href="#directio">directio</a>,
-otherwise reading will be blocking:
-<blockquote><pre>
-location /video/ {
-    aio            on;
-    directio       512;
-    output_buffers 1 128k;
-}
-</pre></blockquote></p><p>
-On Linux,
-<a href="#directio">directio</a>
-can only be used for reading blocks that are aligned on 512-byte
-boundaries (or 4K for XFS).
-Reading of unaligned file's end is still made in blocking mode.
-The same holds true for byte range requests, and for FLV requests
-not from the beginning of a file: reading of unaligned data at the
-beginning and end of a file will be blocking.
-There is no need to turn off
-<a href="#sendfile">sendfile</a>
-explicitly as it is turned off automatically when
-<a href="#directio">directio</a>
-is used.

-Defines a replacement for the specified location.
-For example, with the following configuration
-<blockquote><pre>
-location /i/ {
-    alias /data/w3/images/;
-}
-</pre></blockquote>
-the request of
-&ldquo;<code>/i/top.gif</code>&rdquo; will be responded
-with the file
-&ldquo;<code>/data/w3/images/top.gif</code>&rdquo;.
-</p><p>
-The <code><i>path</i></code> value can contain variables.
-</p><p>
-If <code>alias</code> is used inside a location defined
-with a regular expression then such regular expression should
-contain captures and <code>alias</code> should refer to
-these captures (0.7.40), for example:
-<blockquote><pre>
-location ~ ^/users/(.+\.(?:gif|jpe?g|png))$ {
-    alias /data/w3/images/$1;
-}
-</pre></blockquote></p><p>
-When location matches the last part of the directive's value:
-<blockquote><pre>
-location /images/ {
-    alias /data/w3/images/;
-}
-</pre></blockquote>
-it is better to use the

-      <code>http</code>, <code>server</code><br><p>
-Sets buffer size for reading client request header.
-For most requests, a buffer of 1K bytes is enough.
-However, if a request includes long cookies, or comes from a WAP client,
-it may not fit into 1K.
-If a request line, or a request header field do not fit entirely into

-Defines the URI that will be shown for the specified errors.
-These directives are inherited from the previous level if and
-only if there are no
-<code>error_page</code>
-directives on
-the current level.
-A URI value can contain variables.
-</p><p>
-Example:
-<blockquote><pre>
-error_page 404         /404.html;
-error_page 502 503 504 /50x.html;
-error_page 403         http://example.com/forbidden.html;

-Furthermore, it is possible to change the response code to another, for example:
-<blockquote><pre>
-error_page 404 =200 /empty.gif;
-</pre></blockquote></p><p>
-If an error response is processed by a proxied server, or a FastCGI server,
-and the server may return different response codes (e.g., 200, 302, 401
-or 404), it is possible to respond with a returned code:
-<blockquote><pre>
-error_page 404 = /404.php;
-</pre></blockquote></p><p>
-If there is no need to change URI during redirection it is possible to redirect
-error processing into a named location:
-<blockquote><pre>

-      <strong>none</strong><br><strong>context</strong>:
-      <code>server</code><br><p>
-Sets a configuration based on a request URI.
-A location can either be defined by a prefix string, or by a regular expression.
-Regular expressions are specified by prepending them with the
-&ldquo;<code>~*</code>&rdquo; prefix (for case-insensitive matching), or with the
-&ldquo;<code>~</code>&rdquo; prefix (for case-sensitive matching).
-To find a location matching a given request, nginx first checks
-locations defined using the prefix strings (prefix locations).
-Amongst them, the most specific one is searched.
-Then regular expressions are checked, in the order of their appearance
-in a configuration file.
-A search terminates on the first match, and its corresponding
-configuration is used.
-If no match with a regular expression location is found then a
-configuration of the most specific prefix location is used.
-</p><p>
-For case-insensitive operating systems such as Mac OS X and Cygwin,
-the string matching ignores a case (0.7.7).
-However, comparison is limited to one-byte locales.
-</p><p>
-Regular expressions can contain captures (0.7.40) that can later
-be used in other directives.
-</p><p>
-If the most specific prefix location has the &ldquo;<code>^~</code>&rdquo; prefix
-then regular expressions are not checked.
-</p><p>
-Also, using the &ldquo;<code>=</code>&rdquo; prefix it is possible to define
-an exact match of URI and location.
-If an exact match is found, the search terminates.
-For example, if a &ldquo;<code>/</code>&rdquo; request happens frequently,
-defining &ldquo;<code>location = /</code>&rdquo; will speed up the processing
-of these requests, as search terminates right after the first
-comparison.
-</p><p>
-In versions from 0.7.1 to 0.8.41, if a request matched the prefix
-location without the &ldquo;<code>=</code>&rdquo; and &ldquo;<code>^~</code>&rdquo;
-prefixes, the search also terminated and regular expressions were
-not checked.
-</p><p>
-Let's illustrate the above by example:
-<blockquote><pre>
-location = / {
-    [ configuration A ]
-}
-
-location / {
-    [ configuration B ]
-}
-
-location ^~ /images/ {
-    [ configuration C ]
-}
-
-location ~* \.(gif|jpg|jpeg)$ {
-    [ configuration D ]
-}
-</pre></blockquote>
-The &ldquo;<code>/</code>&rdquo; request will match configuration A,
-the &ldquo;<code>/documents/document.html</code>&rdquo; request will match
-configuration B,
-the &ldquo;<code>/images/1.gif</code>&rdquo; request will match configuration C, and
-the &ldquo;<code>/documents/1.jpg</code>&rdquo; request will match configuration D.
-</p><p>
-The &ldquo;<code>@</code>&rdquo; prefix defines a named location.
-Such a location is not used for a regular request processing, but instead
-used for request redirection.

-Enables or disables compression of two or more adjacent slashes
-in a URI into a single slash.
-</p><p>
-Note that compression is essential for the correct prefix string
-and regular expressions location matching.
-Without it, the &ldquo;<code>//scripts/one.php</code>&rdquo; request would not match
-<blockquote><pre>
-location /scripts/ {
-    ...
-}
-</pre></blockquote>
-and might be processed as a static file,
-so it gets converted to &ldquo;<code>/scripts/one.php</code>&rdquo;.
-</p><p>
-Turning the compression <code>off</code> can become necessary if a URI

-Sets names of the virtual server, for example:
-<blockquote><pre>
-server {
-    server_name example.com www.example.com;
-}
-</pre></blockquote></p><p>
-The first name becomes a primary server name.
-By default, the machine's hostname is used.
-Server names can include an asterisk (&ldquo;<code>*</code>&rdquo;)
-to replace the first or last part of a name:
-<blockquote><pre>
-server {
-    server_name example.com *.example.com www.example.*;
-}
-</pre></blockquote></p><p>
-The first two of the above mentioned names can be combined:
-<blockquote><pre>
-server {
-    server_name .example.com;
-}
-</pre></blockquote></p><p>
-It is also possible to use regular expressions in server names,
-prepending the name with a tilde (&ldquo;<code>~</code>&rdquo;):
-<blockquote><pre>
-server {
-    server_name www.example.com ~^www\d+\.example\.com$;
-}
-</pre></blockquote></p><p>
-Regular expressions can contain captures (0.7.40) that can later
-be used in other directives:
-<blockquote><pre>
-server {
-    server_name ~^(www\.)?(.+)$;
-
-    location / {
-        root /sites/$2;
-    }

-    server_name _;
-
-    location / {
-        root /sites/default;
-    }
-}
-</pre></blockquote></p><p>
-Starting from version 0.8.25, named captures in regular expressions create
-variables that can later be used in other directives:
-<blockquote><pre>
-server {
-    server_name ~^(www\.)?(?&lt;domain&gt;.+)$;
-
-    location / {
-        root /sites/$domain;

-Starting from version 0.7.11, it is possible to specify an empty name:
-<blockquote><pre>
-server {
-    server_name www.example.com "";

-<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>HTTP MP4 Module</title></head><body><center><h3>HTTP MP4 Module</h3></center><center><h4>Summary</h4></center><p>
-The module <code>ngx_http_mp4_module</code> provides pseudo-streaming
-server-side support for H.264/AAC files typically having filename extensions
-<code>.mp4</code>, <code>.m4v</code>,
-and <code>.m4a</code>.
-</p><p>
-Pseudo-streaming works in alliance with conformant Flash players.
-A player sends an HTTP request to the server with a start time
-argument in the request URI’s query string (named simply
-<code>start</code>
-and specified in seconds), and the server responds with a stream
-so that its start position corresponds to the requested time,
-for example:
-<blockquote><pre>
-http://example.com/elephants_dream.mp4?start=238.88
-</pre></blockquote>
-This allows for a random seeking at any time, or starting playback
-in the middle of a timeline.
-</p><p>
-To support seeking, H.264-based formats store the metadata
-in the so-called “moov atom.”
-It is a part of the file that holds the index information for the
-whole file.
-</p><p>
-To start playback, a player first needs to read metadata.
-This is done by sending a special request with the
-<code>start=0</code>
-argument.  Many encoding software will insert the metadata at
-the end of the file.  This is bad for pseudo-streaming:
-the metadata needs to be located at the beginning of the file,
-or else the entire file will have to be downloaded before it
-starts playing.  If a file is well-formed (with metadata at the
-beginning of a file), nginx just sends back the contents of a file.
-Otherwise, it has to read the file and prepare a new stream so that
-metadata comes before media data.
-This involves some CPU, memory, and disk I/O overhead,
-so it is a good idea to
-<a href="http://flowplayer.org/plugins/streaming/pseudostreaming.html#prepare">
-prepare an original file for pseudo-streaming</a>,
-rather than having nginx do this on every such request.
-</p><p>
-For a matching request with a non-zero
-<code>start</code>
-argument, nginx will read metadata from the file, prepare the
-stream starting from the requested offset, and send it to a client.
-This has the same overhead as described above.
-</p><p>
-If a matching request does not include the
-<code>start</code>
-argument, there is no overhead, and the file is just sent as a static resource.
-Some players also support byte-range requests, and thus do not require
-this module at all.
-</p><p>
-This module is not built by default, it should be enabled with the
-<code>--with-http_mp4_module</code>
-configuration parameter.
-
-If you were using the third-party mp4 module, be sure to disable it.
-</p><p>
-A similar pseudo-streaming support for FLV files is provided by the module
-<a href="ngx_http_flv_module.html">ngx_http_flv_module</a>.
-</p><a name="example"></a><center><h4>Example Configuration</h4></center><p><blockquote><pre>

-<para>
-Enables or disables the use of asynchronous file I/O (AIO)
-on FreeBSD and Linux.
-</para>
-
-<para>
-On FreeBSD, AIO is usable starting from FreeBSD&nbsp;4.3.
-AIO can either be linked statically into a kernel:
-<example>
-options VFS_AIO
-</example>
-or loaded dynamically as a kernel loadable module:
-<example>
-kldload aio
-</example>
-</para>
-
-<para>
-In FreeBSD versions 5 and 6, enabling AIO statically, or dynamically
-when booting the kernel, will cause the entire networking subsystem
-to use the Giant lock that can impact overall performance negatively.
-This limitation has been removed in FreeBSD&nbsp;6.4-STABLE in 2009, and in
-FreeBSD&nbsp;7.
-However, starting from FreeBSD&nbsp;5.3 it is possible to enable AIO
-without the penalty of running the networking subsystem under a
-Giant lock&mdash;for this to work, the AIO module needs to be loaded
-after the kernel has booted.
-In this case, the following message will appear in
-<pathname>/var/log/messages</pathname>
-<example>
-WARNING: Network stack Giant-free, but aio requires Giant.
-Consider adding 'options NET_WITH_GIANT' or setting debug.mpsafenet=0
-</example>
-and can safely be ignored.
-<note>
-The requirement to use the Giant lock with AIO is related to the
-fact that FreeBSD supports asynchronous calls
-<c-func>aio_read</c-func>
-and
-<c-func>aio_write</c-func>
-when working with sockets.
-However, since nginx only uses AIO for disk I/O, no problems should arise.
-</note>
-</para>
-
-<para>
-For AIO to work,
-<link id="sendfile">sendfile</link>
-needs to be disabled:
-<example>
-location /video/ {
-    sendfile       off;
-    aio            on;
-    output_buffers 1 64k;
-}
-</example>
-</para>
-
-<para>
-In addition, starting from FreeBSD&nbsp;5.2.1 and nginx&nbsp;0.8.12, AIO can
-also be used to pre-load data for <c-func>sendfile</c-func>:
-<example>
-location /video/ {
-    sendfile       on;
-    tcp_nopush     on;
-    aio            sendfile;
-}
-</example>
-In this configuration, <c-func>sendfile</c-func> is called with
-the <c-def>SF_NODISKIO</c-def> flag which causes it not to
-block on disk I/O and instead report back when the data are not in
-memory; nginx then initiates an asynchronous data load by reading
-one byte. The FreeBSD kernel then loads the first 128K bytes
-of a file into memory, however next reads will only load data
-in 16K chunks. This can be tuned using the
-<link id="read_ahead">read_ahead</link>
-directive.
-</para>
-
-<para>
-On Linux, AIO is usable starting from kernel version 2.6.22;
-plus, it is also necessary to enable
-<link id="directio">directio</link>,
-otherwise reading will be blocking:
-<example>
-location /video/ {
-    aio            on;
-    directio       512;
-    output_buffers 1 128k;
-}
-</example>
-</para>
-
-<para>
-On Linux,
-<link id="directio">directio</link>
-can only be used for reading blocks that are aligned on 512-byte
-boundaries (or 4K for XFS).
-Reading of unaligned file's end is still made in blocking mode.
-The same holds true for byte range requests, and for FLV requests
-not from the beginning of a file: reading of unaligned data at the
-beginning and end of a file will be blocking.
-There is no need to turn off
-<link id="sendfile">sendfile</link>
-explicitly as it is turned off automatically when
-<link id="directio">directio</link>
-is used.

-
-<para>
-The <argument>path</argument> value can contain variables.
-</para>
-
-<para>
-If <code>alias</code> is used inside a location defined
-with a regular expression then such regular expression should
-contain captures and <code>alias</code> should refer to

-location ~ ^/users/(.+\.(?:gif|jpe?g|png))$ {
-    alias /data/w3/images/$1;
-}

-Sets a configuration based on a request URI.
-A location can either be defined by a prefix string, or by a regular expression.
-Regular expressions are specified by prepending them with the
-<dq><value>~*</value></dq> prefix (for case-insensitive matching), or with the
-<dq><value>~</value></dq> prefix (for case-sensitive matching).
-To find a location matching a given request, nginx first checks
-locations defined using the prefix strings (prefix locations).
-Amongst them, the most specific one is searched.
-Then regular expressions are checked, in the order of their appearance
-in a configuration file.
-A search terminates on the first match, and its corresponding
-configuration is used.
-If no match with a regular expression location is found then a
-configuration of the most specific prefix location is used.
-</para>
-
-<para>
-For case-insensitive operating systems such as Mac OS X and Cygwin,
-the string matching ignores a case (0.7.7).
-However, comparison is limited to one-byte locales.

-If the most specific prefix location has the <dq><value>^~</value></dq> prefix
-then regular expressions are not checked.
-</para>
-
-<para>
-Also, using the <dq><value>=</value></dq> prefix it is possible to define
-an exact match of URI and location.
-If an exact match is found, the search terminates.
-For example, if a <dq><code>/</code></dq> request happens frequently,
-defining <dq><code>location = /</code></dq> will speed up the processing
-of these requests, as search terminates right after the first
-comparison.

-In versions from 0.7.1 to 0.8.41, if a request matched the prefix
-location without the <dq><value>=</value></dq> and <dq><value>^~</value></dq>
-prefixes, the search also terminated and regular expressions were
-not checked.

-location ^~ /images/ {

-
-location ~* \.(gif|jpg|jpeg)$ {

-</example>
-The <dq><code>/</code></dq> request will match configuration A,
-the <dq><code>/documents/document.html</code></dq> request will match
-configuration B,
-the <dq><code>/images/1.gif</code></dq> request will match configuration C, and
-the <dq><code>/documents/1.jpg</code></dq> request will match configuration D.
-</para>
-

-The <dq><value>@</value></dq> prefix defines a named location.

-<para>
-The module <code>ngx_http_mp4_module</code> provides pseudo-streaming
-server-side support for H.264/AAC files typically having filename extensions
-<pathname>.mp4</pathname>, <pathname>.m4v</pathname>,
-and <pathname>.m4a</pathname>.
-</para>
-
-<para>
-Pseudo-streaming works in alliance with conformant Flash players.
-A player sends an HTTP request to the server with a start time
-argument in the request URI’s query string (named simply
-<parameter>start</parameter>
-and specified in seconds), and the server responds with a stream
-so that its start position corresponds to the requested time,
-for example:
-<example>
-http://example.com/elephants_dream.mp4?start=238.88
-</example>
-This allows for a random seeking at any time, or starting playback
-in the middle of a timeline.
-</para>
-
-<para>
-To support seeking, H.264-based formats store the metadata
-in the so-called “moov atom.”
-It is a part of the file that holds the index information for the
-whole file.
-</para>
-
-<para>
-To start playback, a player first needs to read metadata.
-This is done by sending a special request with the
-<parameter>start=0</parameter>
-argument.  Many encoding software will insert the metadata at
-the end of the file.  This is bad for pseudo-streaming:
-the metadata needs to be located at the beginning of the file,
-or else the entire file will have to be downloaded before it
-starts playing.  If a file is well-formed (with metadata at the
-beginning of a file), nginx just sends back the contents of a file.
-Otherwise, it has to read the file and prepare a new stream so that
-metadata comes before media data.
-This involves some CPU, memory, and disk I/O overhead,
-so it is a good idea to
-<link url="http://flowplayer.org/plugins/streaming/pseudostreaming.html#prepare">
-prepare an original file for pseudo-streaming</link>,
-rather than having nginx do this on every such request.
-</para>
-
-<para>
-For a matching request with a non-zero
-<parameter>start</parameter>
-argument, nginx will read metadata from the file, prepare the
-stream starting from the requested offset, and send it to a client.
-This has the same overhead as described above.
-</para>
-
-<para>
-If a matching request does not include the
-<parameter>start</parameter>
-argument, there is no overhead, and the file is just sent as a static resource.
-Some players also support byte-range requests, and thus do not require
-this module at all.
-</para>
-
-<para>
-This module is not built by default, it should be enabled with the
-<code>--with-http_mp4_module</code>
-configuration parameter.

-If you were using the third-party mp4 module, be sure to disable it.
