VIP Persistence

Have a look at the LDAP Proxy iRule in the codeshare. It demonstrates an LDAP proxy (An HTTP version I think is what you're really after for your case). It shows how to reconnect to another poolmember and continue the client-f5 connection without the client knowing about it.

 

 

You'll have to rip out the LDAP binding of course, and intercept the poolmember failure as well... (Because the LDAP Proxy iRule swaps back & forth between read-only and read-write backends, it doesn't account for server failure).

 

 

I think you'll want to look at using the SERVER_CLOSED event to detect the server side connection going down. And then reselect a new pool member in there.
