CirrostratusI assume the protocol runs over TCP? You can do most of that with iRule functionaliy:
1. Collect the TCP data in the request, using TCP::collect (Click here).
2. Parse the data using TCP::payload (Click here).
3. Check the session table for an existing entry, and send the request to that node. If there isn't an entry, add one (Click here). The session table entry would include the string, pool member and a timeout.
The last requirement to flush the table every 24 hours would probably need to be done using an iControl app (Click here). I don't know of a way to get the current time with the TCL commands enabled in iRules.
