From e154edd8078020d6eba41b448afade0a68617f35 Mon Sep 17 00:00:00 2001 From: Lars Hjemli Date: Sat, 9 Aug 2008 21:11:41 +0200 Subject: Teach cgit how to use PATH_INFO This commit makes cgit use the cgi variables SCRIPT_NAME and PATH_INFO when virtual-root is unspecified in cgitrc and no url-parameter is specified on the querystring. This has two nice effects: * Virtual urls works out of the box, no more need for rewrite-rules in httpd. * Virtual urls with special querystring characters are handled correctly.
