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_object, $header_to_modify )
           This  function tries to guess media type and encoding for a file or objects that support the a "path"
           or "filename" method, eg, URI or File::Temp objects.  When an object does not support either  method,
           it  will  be  stringified  to determine the filename.  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");
