Forcing auto_prepend_file to work regardless of what document was accessed

Hello, all - Anyone know if it's possible to use auto_prepend_file to force the appending of a file to the request, regardless of what kind of document is generated? I can see this being a problem if the document was a picture or a video or some such - but is thre a hidden argument list to auto_prepend_file where I can force inclusion of this file, if x, y, and z document types were requested? Thanks! -dant
