Redirecting requests for the non www version of your domain to the www version only can help to boost your SEO, eliminate duplicate search engine entries and improve your ranking. And it is easy to do with Apache and mod_rewrite.

You just finished your install of Apache, PHP and APC cache on a VPS and you're beat. You spent about a day going over every configuration and compile option trying to eek performance out of your VPS machine and web server. Then you take a look at the output of top or ps and notice, hey, my Apache process is 150 Megs! Well isn't that grand....

Drupal multisite setup configuration

I've adopted Drupal for a majority of my online activities in the past year. It has enough of the things I like and is much faster and more stable than previous CMS or forum software I've used. However, some documentation seems to be lacking. Multisite configuration with Apache using a single Drupal codebase is one area.

I finally decided to try a project in which I would use a common codebase for Drupal across all of my websites. That is, rather than having a directory for each website that has a Drupal installation in it, I thought I would take advantage of Drupal's multisite functionality by having one drupal installation (codebase) in a central directory and have all the project websites point to it.
