Nothing to do with keepAlive. PHP generates a 'handle' to some data stored
server-side (in a file by default) which is automagically loaded by PHP
when a PHP page is hit with a valid handle in the request.
Typically this is passed to the client as a cookie, and therefore requires
that PHP be able to set headers. Having never heard of "Nevrona's Indy" I
would take a guess that it's a header issue.
RTFM for more info on sessions - see also setcookie for testing.
