- <H1><A NAME="description">DESCRIPTION</A></H1>
- <P>This module provides functions for handling media (also known as
- MIME) types and encodings. The mapping from file extentions to media
- types is defined by the <EM>media.types</EM> file. If the <EM>~/.media.types</EM>
- file exists it is used instead.
- For backwards compatability we will also look for <EM>~/.mime.types</EM>.</P>
- <P>The following functions are exported by default:</P>
- <DL>
- <DT><STRONG><A NAME="item_guess_media_type">guess_media_type($filename_or_url, [$header_to_modify])</A></STRONG><BR>
- <DD>
- This function tries to guess media type and encoding for a file or url.
- It returns the content-type, which is a string like <CODE>"text/html"</CODE>.
- In array context it also returns any content-encodings applied (in the
- order used to encode the file). You can pass a URI object
- reference, instead of the file name.
- <P>If the type can not be deduced from looking at the file name,
- then <A HREF="#item_guess_media_type"><CODE>guess_media_type()</CODE></A> will let the <CODE>-T</CODE> Perl operator take a look.
- If this works (and <CODE>-T</CODE> returns a TRUE value) then we return
- <EM>text/plain</EM> as the type, otherwise we return
- <EM>application/octet-stream</EM> as the type.</P>
- <P>The optional second argument should be a reference to a HTTP::Headers
- object or any object that implements the $obj->header method in a
- similar way. When it is present the values of the
- 'Content-Type' and 'Content-Encoding' will be set for this header.</P>
- <P></P>
- <DT><STRONG><A NAME="item_media_suffix"><CODE>media_suffix($type,...)</CODE></A></STRONG><BR>
- <DD>
- This function will return all suffixes that can be used to denote the
- specified media type(s). Wildcard types can be used. In a scalar
- context it will return the first suffix found.
- <P>Examples:</P>
- <PRE>
- @suffixes = media_suffix('image/*', 'audio/basic');
- $suffix = media_suffix('text/html');</PRE>
- <P></P></DL>
- <P>The following functions are only exported by explict request:</P>
- <DL>
- <DT><STRONG><A NAME="item_add_type">add_type($type, @exts)</A></STRONG><BR>
- <DD>
- Associate a list of file extensions with the given media type.
- <P>Example:</P>
- <PRE>
- add_type("x-world/x-vrml" => qw(wrl vrml));</PRE>
- <P></P>
- <DT><STRONG><A NAME="item_add_encoding">add_encoding($type, @ext)</A></STRONG><BR>
- <DD>
- Associate a list of file extensions with an encoding type.
- <P>Example:</P>
- <PRE>
- add_encoding("x-gzip" => "gz");</PRE>
- <P></P>
- <DT><STRONG><A NAME="item_read_media_types"><CODE>read_media_types(@files)</CODE></A></STRONG><BR>
- <DD>
- Parse media types files and add the type mappings found there.
- <P>Example:</P>
- <PRE>
- read_media_types("conf/mime.types");</PRE>
