Name

mod_rewrite — http(8gx) handler for altering HTTP request URIs before processing

Description

mod_rewrite can alter request URIs. It runs before any of the other built-in or HTTP processing modules.

Configuration directives

This component shares http.cfg. See http(8gx).

Rewrite map

The filemap that specifies which URIs to handle is rewrite.txt, which is searched for in config_file_path. The usual location is /etc/gromox/rewrite.txt.

Each line in this file consists of 3 columns separated by whitespace:

A POSIX Basic Regular Expression (cf. regcomp(3)) for matching the original URI. For safety, this should always be anchored with the beginning-of-line metacharacter (^; circumflex).
The fixed sequence "=>".
Replacement string. Captures can be spliced using \1, \2, etc. The sequence \0 splices the entire string (equivalent of Perl's $&). If a particular pattern has successfully matched, no other rewrite rules are processed.

If the file has no lines, no paths will be rewritten. If the file is absent however, a set of default entries will be used.

Default rules

^/Microsoft-Server-ActiveSync(/\|$) => /sync/index.php

Examples

^/([a-z+])/([a-z]+).txt$ => /\2/\1.txt
