Adding the www to URL in .htaccess for hosting multiple domain or multisites and handle www issue for canonical URLs.

    ##Adding the www

    RewriteCond %{HTTP_HOST} !^www\. [NC]

How to install YUM, Zend Optimizer, eAccelerator and APC

Recently a friend had difficulty installing Alternative PHP Cache (APC) and upload progress for his Drupal CMS on Debian VPS. Therefore I tought of sharing this post about how to setup and run your virtual private server with most useful PHP packages.

I would assume you have a Debian VPS, CentOs or Ubuntu and you would like to install APC, Zend Optimizer and eAccelerator for the best PHP performances or if they are required by some third party applications.

I normally like to install everything on Debian, CentOs or Ubuntu using the yum (Yellow dog Updater, Modified) package manger to make sure that updates for all applications are uniform and its easy to do, easy to search for available packages and easier to type instead of apt-get.
