            Dear hackers,

     Up until now, I had a setup with 4-5 webservers, one 'main' server on
     which all the changes to the websites were done, and the rest which
     were rsync-ing the web repository to the local drives. The content is
     either static or dynamic (PHP). Of course, I was load balancing (DNS
     round-robin) only the statical domains, and the ones involving PHP
     scripts which fetched all the informations from a database. The
     domains which involved PHP sessions were left on the 'main' server.

     Right now I am considering a setup with one common NFS repository for
     the configuration files, Apache binaries, Web content and temp
     directory for PHP, NFS resource which will be mounted on all the
     'front' webservers. I am wondering, though, if I will be able (by
     having one common temp directory for PHP) to load-balance the domains
     involving sessions: will the sessions be lost when connsecutive hits
     go to different webservers, or not?

     I will also be interested in finding out more opinions about this
     sort of setup (interested in what are the pitfalls of the common NFS
     repository) from the people who already got it implemented.

     Thank you,
     bogdan
