Requirements

This module works properly only with mod_php and prefork MPM.

Overview

The main idea is simple, just use this module together with reverse proxy in front of Apache. Set custom headers from reverse proxy and manage php.ini values, DocumentRoot, ServerName according to headers. For instance you set ResetHeaders "open_basedir" "X-Document-Root" and this will set open_basedir on the fly to value from X-Document-Root header.

Compile

make
make ruid (with mod_ruid2 support)
make nophp (without php support)
make clean
make CFLAGS=-DMOD_RESET_AUTH_KEY='\\\"secret\\\"' (if validation is needed between client/server)

Install

!!! IMPORTANT !!! This module MUST be loaded after mod_php.

LoadModule reset_module /usr/lib64/httpd/modules/mod_reset.so
