<summary>

<p>This module is used to assign content metadata to the content

selected for an HTTP response by mapping patterns in the

URI or filenames to the metadata values. For example, the filename

extensions of content files often define the content's Internet

media type, language, character set, and content-encoding. This

information is sent in HTTP messages containing that content and

used in content negotiation when selecting alternatives, such that

the user's preferences are respected when choosing one of several

possible contents to serve. See

<module>mod_negotiation</module> for more information

about <a href="/content-negotiation.html">content negotiation</a>.</p>

<p>The directives <directive

module="mod_mime">AddCharset</directive>, <directive

module="mod_mime">AddEncoding</directive>, <directive

module="mod_mime">AddLanguage</directive> and <directive

module="mod_mime">AddType</directive> are all used to map file

extensions onto the metadata for that file. Respectively

they set the character set, content-encoding, content-language,

and <glossary>media-type</glossary> (content-type) of documents. The directive <directive

module="mod_mime">TypesConfig</directive> is used to specify a

file which also maps extensions onto media types. </p>

<p>In addition, <module>mod_mime</module> may define the <a

href="/handler.html">handler</a> and <a

href="/filter.html">filters</a> that originate and process

content. The directives <directive

module="mod_mime">AddHandler</directive>, <directive

module="mod_mime">AddOutputFilter</directive>, and <directive

module="mod_mime">AddInputFilter</directive> control the modules

or scripts that serve the document. The <directive

module="mod_mime">MultiviewsMatch</directive> directive allows

<module>mod_negotiation</module> to consider these file extensions

to be included when testing Multiviews matches.</p>

<p>While <module>mod_mime</module> associates metadata

with filename extensions, the <module>core</module> server

provides directives that are used to associate all the files in a

given container (<em>e.g.</em>, <directive type="section"

module="core">Location</directive>, <directive type="section"

module="core">Directory</directive>, or <directive type="section"

module="core">Files</directive>) with particular

metadata. These directives include <directive

module="core">ForceType</directive>, <directive

module="core">SetHandler</directive>, <directive

module="core">SetInputFilter</directive>, and <directive

module="core">SetOutputFilter</directive>. The core directives

override any filename extension mappings defined in

<module>mod_mime</module>.</p>

<p>Note that changing the metadata for a file does not

change the value of the <code>Last-Modified</code> header.

Thus, previously cached copies may still be used by a client or

proxy, with the previous headers. If you change the

metadata (language, content type, character set or

encoding) you may need to 'touch' affected files (updating

their last modified date) to ensure that all visitors are

receive the corrected content headers.</p>

<section id="multipleext"><title>Files with Multiple Extensions</title>

<p>Files can have more than one extension; the order of the

extensions is <em>normally</em> irrelevant. For example, if the

file <code>welcome.html.fr</code> maps onto content type

<code>text/html</code> and language French then the file

<code>welcome.fr.html</code> will map onto exactly the same

information. If more than one extension is given that maps onto

the same type of metadata, then the one to the right will

be used, except for languages and content encodings. For example,

if <code>.gif</code> maps to the <glossary>media-type</glossary>

<code>image/gif</code> and <code>.html</code> maps to the

media-type <code>text/html</code>, then the file

<code>welcome.gif.html</code> will be associated with the

media-type <code>text/html</code>.</p>

<p><a href="#charset-lang">Languages</a> and <a href="#contentencoding"

>content encodings</a> are treated accumulative, because one can assign

more than one language or encoding to a particular resource. For example,

the file <code>welcome.html.en.de</code> will be delivered with

<code>Content-Language: en, de</code> and <code>Content-Type:

text/html</code>.</p>

<p>Care should be taken when a file with multiple extensions

gets associated with both a <glossary>media-type</glossary>

and a handler. This will

usually result in the request being handled by the module associated

with the handler. For example, if the <code>.imap</code>

extension is mapped to the handler <code>imap-file</code> (from

<module>mod_imagemap</module>) and the <code>.html</code> extension is

mapped to the media-type <code>text/html</code>, then the file

<code>world.imap.html</code> will be associated with both the

<code>imap-file</code> handler and <code>text/html</code> media-type.

When it is processed, the <code>imap-file</code> handler will be used,

and so it will be treated as a <module>mod_imagemap</module> imagemap

file.</p>

<p>If you would prefer only the last dot-separated part of the

filename to be mapped to a particular piece of meta-data, then do

not use the <code>Add*</code> directives. For example, if you wish

to have the file <code>foo.html.cgi</code> processed as a CGI

script, but not the file <code>bar.cgi.html</code>, then instead

of using <code>AddHandler cgi-script .cgi</code>, use</p>

<example><title>Configure handler based on final extension only</title>

<highlight language="config">

&lt;FilesMatch "[^.]+\.cgi$"&gt;

SetHandler cgi-script

&lt;/FilesMatch&gt;

</highlight>

</example>

</section>

<section id="contentencoding"><title>Content encoding</title>

<p>A file of a particular <glossary>media-type</glossary> can additionally be encoded a

particular way to simplify transmission over the Internet.

While this usually will refer to compression, such as

<code>gzip</code>, it can also refer to encryption, such a

<code>pgp</code> or to an encoding such as UUencoding, which is

designed for transmitting a binary file in an ASCII (text)

format.</p>

<p>The <a href="http://www.ietf.org/rfc/rfc2616.txt">HTTP/1.1

RFC</a>, section 14.11 puts it this way:</p>

<blockquote cite="http://www.ietf.org/rfc/rfc2616.txt">

<p>The Content-Encoding entity-header field is used as a modifier to

the media-type. When present, its value indicates what additional

content codings have been applied to the entity-body, and thus what

decoding mechanisms must be applied in order to obtain the media-type

referenced by the Content-Type header field. Content-Encoding is

primarily used to allow a document to be compressed without losing

the identity of its underlying media type.</p>

</blockquote>

<p>By using more than one file extension (see <a

href="#multipleext">section above about multiple file

extensions</a>), you can indicate that a file is of a

particular <em>type</em>, and also has a particular

<em>encoding</em>. </p>

<p>For example, you may have a file which is a Microsoft Word

document, which is pkzipped to reduce its size. If the

<code>.doc</code> extension is associated with the Microsoft

Word file type, and the <code>.zip</code> extension is

associated with the pkzip file encoding, then the file

<code>Resume.doc.zip</code> would be known to be a pkzip'ed Word

document.</p>

<p>Apache sends a <code>Content-encoding</code> header with the

resource, in order to tell the client browser about the

encoding method.</p>

<highlight language="config">

Content-encoding: pkzip

</highlight>

</section>

<section id="charset-lang"><title>Character sets and languages</title>

<p>In addition to file type and the file encoding,

another important piece of information is what language a

particular document is in, and in what character set the file

should be displayed. For example, the document might be written

in the Vietnamese alphabet, or in Cyrillic, and should be

displayed as such. This information, also, is transmitted in

HTTP headers.</p>

<p>The character set, language, encoding and mime type are all

used in the process of content negotiation (See

<module>mod_negotiation</module>) to determine

which document to give to the client, when there are

alternative documents in more than one character set, language,

encoding or mime type. All filename extensions associations

created with <directive module="mod_mime">AddCharset</directive>,

<directive module="mod_mime">AddEncoding</directive>, <directive

module="mod_mime">AddLanguage</directive> and <directive

module="mod_mime">AddType</directive> directives

(and extensions listed in the <directive module="mod_mime_magic"

>MimeMagicFile</directive>) participate in this select process.

Filename extensions that are only associated using the <directive

module="mod_mime">AddHandler</directive>, <directive module="mod_mime"

>AddInputFilter</directive> or <directive module="mod_mime"

>AddOutputFilter</directive> directives may be included or excluded

from matching by using the <directive module="mod_mime"

>MultiviewsMatch</directive> directive.</p>

<section id="charset"><title>Charset</title>

<p>To convey this further information, Apache optionally sends

a <code>Content-Language</code> header, to specify the language

that the document is in, and can append additional information

onto the <code>Content-Type</code> header to indicate the

particular character set that should be used to correctly

render the information.</p>

<example>

Content-Language: en, fr

Content-Type: text/plain; charset=ISO-8859-1

</example>

<p>The language specification is the two-letter abbreviation

for the language. The <code>charset</code> is the name of the

particular character set which should be used.</p>

to be marked as encoded using the <code>x-gzip</code> encoding, and

filenames containing the <code>.Z</code> extension to be marked as

<p>Old clients expect <code>x-gzip</code> and <code>x-compress</code>,

however the standard dictates that they're equivalent to

<code>gzip</code> and <code>compress</code> respectively. Apache does

content encoding comparisons by ignoring any leading <code>x-</code>.

When responding with an encoding Apache will use whatever form

(<em>i.e.</em>, <code>x-foo</code> or <code>foo</code>) the

client requested. If the client didn't specifically request a

particular form Apache will use the form given by the

<code>AddEncoding</code> directive. To make this long story

short, you should always use <code>x-gzip</code> and

<code>x-compress</code> for these two specific encodings. More

recent encodings, such as <code>deflate</code>, should be

specified without the <code>x-</code>.</p>

<override>FileInfo</override>

<usage>

<p><directive>MultiviewsMatch</directive> permits three different

behaviors for <a href="mod_negotiation.html">mod_negotiation</a>'s

Multiviews feature. Multiviews allows a request for a file,

<em>e.g.</em> <code>index.html</code>, to match any negotiated

extensions following the base request, <em>e.g.</em>

<code>index.html.en</code>, <code>index.html.fr</code>, or

<code>index.html.gz</code>.</p>

<p>The <code>NegotiatedOnly</code> option provides that every extension

following the base name must correlate to a recognized

<module>mod_mime</module> extension for content negotiation, <em>e.g.</em>

Charset, Content-Type, Language, or Encoding. This is the strictest

implementation with the fewest unexpected side effects, and is the

default behavior.</p>

<p>To include extensions associated with Handlers and/or Filters,

set the <directive>MultiviewsMatch</directive> directive to either

<code>Handlers</code>, <code>Filters</code>, or both option keywords.

If all other factors are equal, the smallest file will be served,

<em>e.g.</em> in deciding between <code>index.html.cgi</code> of 500

bytes and <code>index.html.pl</code> of 1000 bytes, the <code>.cgi</code>

file would win in this example. Users of <code>.asis</code> files

might prefer to use the Handler option, if <code>.asis</code> files are

associated with the <code>asis-handler</code>.</p>

<p>You may finally allow <code>Any</code> extensions to match, even if

<module>mod_mime</module> doesn't recognize the extension. This can cause

unpredictable results, such as serving .old or .bak files the webmaster

never expected to be served.</p>

<p>For example, the following configuration will allow handlers

and filters to participate in Multviews, but will exclude unknown

files:</p>

<name>ModMimeUsePathInfo</name>

<description>Tells <module>mod_mime</module> to treat <code>path_info</code>

components as part of the filename</description>

<syntax>ModMimeUsePathInfo On|Off</syntax>

<default>ModMimeUsePathInfo Off</default>

<contextlist><context>directory</context></contextlist>

<usage>

<p>The <directive>ModMimeUsePathInfo</directive> directive is used to

combine the filename with the <code>path_info</code> URL component to

apply <module>mod_mime</module>'s directives to the request. The default

value is <code>Off</code> - therefore, the <code>path_info</code>

component is ignored.</p>

<p>This directive is recommended when you have a virtual filesystem.</p>

<example><title>Example</title>

<highlight language="config">

ModMimeUsePathInfo On

</highlight>

</example>

<p>If you have a request for <code>/index.php/foo.shtml</code>

<module>mod_mime</module> will now treat the

incoming request as <code>/index.php/foo.shtml</code> and directives

like <code>AddOutputFilter INCLUDES .shtml</code> will add the

<code>INCLUDES</code> filter to the request. If <directive

>ModMimeUsePathInfo</directive> is not set, the

<code>INCLUDES</code> filter will not be added. This will work

analogously for virtual paths, such as those defined by

<directive type="section">Location</directive></p>

<name>TypesConfig</name>

<description>The location of the <code>mime.types</code> file</description>

<syntax>TypesConfig <var>file-path</var></syntax>

<default>TypesConfig conf/mime.types</default>

<contextlist><context>server config</context></contextlist>

<usage>

<p>The <directive>TypesConfig</directive> directive sets the

location of the <glossary ref="media-type">media types</glossary>

configuration file. <var>File-path</var> is relative to the

<directive module="core">ServerRoot</directive>. This file sets

the default list of mappings from filename extensions to content

types. Most administrators use the <code>mime.types</code> file

provided by their OS, which associates common filename

extensions with the official list of IANA registered media types

maintained at <a href=

"http://www.iana.org/assignments/media-types/index.html"

>http://www.iana.org/assignments/media-types/index.html</a>

as well as a large number of unofficial types. This

simplifies the <code>httpd.conf</code> file by providing the

majority of media-type definitions, and may be overridden by

<directive module="mod_mime">AddType</directive> directives as

needed. You should not edit the <code>mime.types</code> file,

because it may be replaced when you upgrade your server.</p>

<p>The file contains lines in the format of the arguments to

an <directive module="mod_mime">AddType</directive> directive:</p>

<example>

<var>media-type</var> [<var>extension</var>] ...

</example>

<p>The case of the extension does not matter. Blank lines, and lines

beginning with a hash character (<code>#</code>) are ignored.

Empty lines are there for completeness (of the mime.types file).

Apache httpd can still determine these types with <module

>mod_mime_magic</module>.

</p>

<note>

Please do <strong>not</strong> send requests to the Apache HTTP

Server Project to add any new entries in the distributed

<code>mime.types</code> file unless (1) they are already

registered with IANA, and (2) they use widely accepted,

non-conflicting filename extensions across platforms.

<code>category/x-subtype</code> requests will be automatically

rejected, as will any new two-letter extensions as they will

likely conflict later with the already crowded language and

character set namespace.
