NAME

       LWP::MediaTypes - guess media type for a file or a URL

SYNOPSIS

        use LWP::MediaTypes qw(guess_media_type);
        $type = guess_media_type("/tmp/foo.gif");

DESCRIPTION

       This module provides functions for handling media (also known as MIME) types and encodings.  The mapping
       from file extensions to media types is defined by the media.types file.  If the ~/.media.types file
       exists it is used instead.  For backwards compatibility we will also look for ~/.mime.types.

       The following functions are exported by default:

       guess_media_type( $filename )
       guess_media_type( $uri )
       guess_media_type( $filename_or_uri, $header_to_modify )
           This  function  tries  to  guess media type and encoding for a file or a URI.  It returns the content
           type, which is a string like "text/html".  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.

           If the type can not be deduced from looking at the file name, then guess_media_type()  will  let  the
           "-T"  Perl  operator  take  a  look.   If  this  works (and "-T" returns a TRUE value) then we return
           text/plain as the type, otherwise we return application/octet-stream as the type.

           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.

       media_suffix( $type, ... )
           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. Examples:

             @suffixes = media_suffix('image/*', 'audio/basic');
             $suffix = media_suffix('text/html');

       The following functions are only exported by explicit request:

       add_type( $type, @exts )
           Associate a list of file extensions with the given media type.  Example:

               add_type("x-world/x-vrml" => qw(wrl vrml));

       add_encoding( $type, @ext )
           Associate a list of file extensions with an encoding type.  Example:

            add_encoding("x-gzip" => "gz");

       read_media_types( @files )
           Parse media types files and add the type mappings found there.  Example:

               read_media_types("conf/mime.types");
