Hi all,

I have a php/mysql website where people can upload their own graphics for
the buttons and background of pages on the website.

This used to run on one server, but I have now been asked to set it up on
multiple servers.

The problem is that when someone uploads a file, how do I distribute it to
all of the servers? Should I use php to send it to all of the servers once
it has been uploaded, or is there a better way of synchronizing the files
between all of the servers?

Also, I am not sure how autologin (based on cookies) and sessions will
work when distributing across multiple servers, as my understanding is
that these are on a per domain basis? (i.e. if someone goes to
node1.site.com and hits autologin, but next time gets node3, the cookie
wont be picked up?)

Any pointers appreciated!

Cheers,

Ben
