Andy, I am pretty sure the remote servers will only be used if the
reals are unavailable (failed healthcheck). I don't thnk max
connections would force that switch.

Mike, and anyone else who is interested...

It does appear that the serveriron is doing the trick. i.e. the local real
servers are filled to max-conn, then subsequent connections are sent to the
server remote-name.

Quite impressed with it really as a Big/IP stalwart that is.

My only problem now appears to be tweaking HTTP Keep-Alives to timeout in
such a way that once you get a succesful connection to the main site, you
keep it, and aren't presented with the too busy pages from the remote server
halfway through your transaction. Should be fun eh ?

Regards

Andy
