title: How to load balance a php application?
body: <p>I am looking for guides, advice, or samples of how to load balance a php application. My setup is Ubuntu 10.04 and PHP 5.3. I have never load balanced servers before and I am looking for any help that is offered.</p>
  
  <p>Update:<br>
  It's a web application that is expected to have a few hundred users using it at the same time. MySQL will be the database. There will be sessions used for the users but I have heard that sessions cannot be carried over multiple servers. There will be very frequent content updates. There will be files but I'll just use a CDN for those.</p>
