NAME

Apache2::MimeInfo - Content-Type header informed by shared-mime-info

VERSION

Version 0.06

SYNOPSIS

PerlLoadModule Apache2::MimeInfo
PerlOutputFilterHandler Apache2::MimeInfo

DESCRIPTION

This module bolts File::MimeInfo::Magic and the shared-mime-info database to Apache 2.x. Its purpose is to clean up Content-Type headers on responses that come from potentially misconfigured or untrustworthy sources (e.g. a proxy).

Insert Apache2::MimeInfo as an output filter as described in the synopsis to perform content-based type checking against a more robust database than the one that comes along with file. The type asserted by the original content handler will be overridden by this filter unless the asserted type is a more specific instance of a more general detected type. For instance, Microsoft's .docx format is a ZIP file with special contents. Its MIME type is this:

application/vnd.openxmlformats-officedocument.wordprocessingml.document

The detector, however, will perceive application/zip, which is an ancestor type. If whatever content handler producing the document asserts the correct type, then this module will do nothing. If, however, it returns something like application/octet-stream, which is even more generic than application/zip, this module will replace the Content-Type header with application/zip. It will likewise replace the Content-Type header if it is missing altogether, or if it asserts a type that is inconsitent with the one which was detected.

If you aren't familiar with shared-mime-info, it's an XML database containing useful information about the mappings of, and relations between MIME types. This means that you can hack new type signatures into it, just as you can with file.
