Apache mod_vhost_alias module fails to set DOCUMENT_ROOT

Jan 12, 2011 By Web Traffic Exchange Linux 0 Last Modified on 2024-01-16

Mass virtual hosting using mod_vhost_alias or mod_rewrite module simplifies pattern-based virtual hosting. However, there is a major problem if your virtual host application makes use of the DOCUMENT_ROOT environment variable. According to the Apache documentation, the mod_vhost_alias does NOT correctly set the DOCUMENT_ROOT variable and hence potentially breaks PHP web applications that make use of this environment variable. It seems that one logical thing to do is to use the VirtualDocumentRoot to map the DOCUMENT_ROOT variable, but current mod_vhost_alias does NOT implement this function and it is very unlikely that it will any time soon.

I spent a whole day trying to figure out a Struts validator problem. It's a web application containing three modules, but only one module does not perform Struts validation. The XML config files are perfectly fine, but no clue was given by the logger or compiler. The log file spits validateInteger error, but no helpful hints whatsoever were given even after turning on the root level logging to DEBUG level.

I have recently acquainted with SuSE Linux, and I looked for a package manager that I can use to manage software packages. I started out with Yast, but it wasn't very good at providing resolutions to dependency problems. Someone recommended Zypper over Yast and yast2, so here I am sharing my experience with Zypper.
