So, do you have updates to the content through the web site or is there an external mechanism to upload new content to the site? If there is an external mechanism, you can modify it to upload the files to both servers. If uploads are handled through the site, you can modify the upload code to take an uploaded file and push it over to the other server. > the problem is keeping the the databases and the web content up to > date on both machines. Also, what about PHP sessions? Have the application redirect to one machine or the other, so a particular user's session will always be on the same server. I.e., a user goes to http://www.yoursite.byu.edu/, and gets redirected to either http://www-a.yoursite.byu.edu/ or http://www-b.yoursite.byu.edu/, which then hands out the session cookie, etc. You will need to adjust your application to live in a replicated environment. As far as handling replication on the MySQL db, some work has been done on clustering techniques. A quick google search for "MySQL clustering" reveals some useful links.
