It looks like the code passes the requested info through to dynamic handlers.

Is this still an issue?

The following patch adds PATH_TRANSLATED_DIRINDEX to the environment when the mod_indexfile target is a path which begins with '/'. This allows CGI, FastCGI, SCGI index generators to know the physical path for which they were called, even after mod_alias translations.

This patch also fixes a bug where con->uri.path was a mishmash of original con->uri.path plus full mod_indexfile target, which was incorrect when the mod_indexfile target began with '/'.

Try using the new PATH_TRANSLATED_DIRINDEX if the index generator path is not relative to the current dir.
