ACE interaction with Server HTTP Persistent Connection

[guan]

Hi Forum,

Question:

If the server implement http persistent connection, which it will generate some kind of keepalives to keep the tcp session open, does ACE has

any interaction here with the server or it just forward the message to server without modifying the msg? What happens if a tcp session is open for long time without any data going over it? Will ACE "close" the "idle" session ?

What happens for SSL when ACE is offloading the servers?

Cheers

ACE will simply pass the tcp keepalives between client and server without changing them.

ACE only monitors packets, not data...So as long as the client or server sends a packet, the connection is maintained on ACE.

But, are you use your servers/clients implement tcp keepalive ?  Have you seen them with a sniffer trace ?

Most people believe there are keepalive because that's the name of a parameter in Apache configuration, but there is actually no "tcp keepalive".
