Cirrostratus
CirrostratusWhat is the purpose of having two virtual servers or two IP's to reference the two servers? Typically, you'd either want to talk to a single high availability IP address (load balanced) or one IP per server for maintenance or similar.
If this is SOAP over HTTP, I'm guessing you'll end up using a new IP for the virtual server and translate the destination IP address to the real server IP. If there is an IP address in the request and/or response payload that needs to be rewritten, you can do this using HTTP::collect (Click here). If the length of the IP address string in the request payload is the same as what you're replacing it with (length of 111.11.11.111 = length of 222.22.22.222), you could use a stream profile and STREAM::expression iRule (Click here) to rewrite the payload. A stream profile and iRule would buffer less payload and be more efficient than using HTTP::collect.
