Mike,

It still could break albeit no fault of Apache. It depends on the
criteria Apache uses for "stickyness". If it relies on an IP address
you may have a problem.

Consider a case where your users are behind a balanced proxy server
that uses sub servers . I personally had an experience where I was
using a web application that would kick me out because the remote
server thought my original session IP had changed (it had!). I found
out that our institutional outbound proxy can arbitrarily call 1 of
3 servers. Our proxy managers are looking for a solution, but this
could be a potential support issue unless your app can set some type
of "sticky" header that Apache might honor instead of using an IP
Address.
