Tag: Software configurations

Last year I set up an Apache 2.2 server on my computer to do some developement work using EzPublish in multiple virtual host environment. One day, I happened to raise a question to Steven on how to get it configured so that mod_rewrite works on my server and I could debug my script locally instead of always having to test it on some remote server. I got the response from him that it does not work in Windows environment. Due to the fact that this particular feature was not critical to the whole operation, I left it as that.

Two days ago out of curiosity, I downloaded this new PHP social networking software called ElGG . Apparently it uses mod_rewrite extensively and provides no other alternative methods to access its function. I was thus forced into a corner. Hence I did what I did. I went to google.com and started researching. Interestingly, I read that some actually got mod_rewrite working on Apache server running on Windows XP.

I spent the next two days researching on the Apache architecture. The result I got was this assuming you already have multiple virtual host setup:

1. uncomment LoadModule rewrite_module modules/mod_rewrite.so in your httpd.conf file
2. add the following lines to your vhost.conf files

   <Directory “…”>
   #Tells your Apache webserver to detect for the .htaccess file in your directory
   AllowOverride All
   </Directory>

3. The below was copied lock stock and barrel from Joomla. Copy and paste it into a .htaccess file on your webserver and place it at the root location
