> I have no PerlReponseHandler, so Apache handles the response…and returns 404. Note that a request for /hi.txt; it’s only a request in a subdirectory, /foo/bar.html, that fails. Why? Why isn’t Apache able to find that file? Is there some other attribute of $r I need to set or unset?

Turns out I was able to fix this issue by unsetting path_info. I just added

    $r->path_info(undef);

To the above code, and now Apache can find the file.

I do not understand the relationship between filename (which is often not the full path to a file) and path_info. Fortunately, it looks like I don’t have to. But we might want to consider updating the docs to recommend unsetting path_info when setting the full path to a file in filename.
