guess media type for a file or a URL

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");
