AOL host name and addresses appear to change midstream of a http post
I have Pix 520's running 6.1.3, using the newer "access-list" convention. I have servers behind them which receive data uploads from my users. The transport is an http post to the server from the client PC. Some of my users dial into AOL. They sign in, start the upload to my server, then it abruptly stops in midstream. The Pix says a PC attempted to send data without sending a SYN to establish a session. And when that happens, from my Cisco/NetScout Ether Probe's point of view, the PC suddenly apprears that it has a different AOL hostname and IP address. All 30 other http applications at this site work just fine.
For whatever reason, this event does not seem to bother my Pixes at another site that are also running 6.1.3, but with the older "static and conduit" convention.
