NimbostratusBalancing transactions on a single connection to different pools
I have a long-running TCP connection over which multiple transactions flow. Every transaction has a value that can be used as a 'key', allowing me to partition the transactions into two groups (e.g. key < 1000; key >= 1000). Is it possible to use an iRule to send 'group1' transactions to one pool and 'group2' to a different pool? The difficulty I'm running into is that I need a single TCP connection from the client side to result in two TCP connections on the F5 -- one to pool1 and one to pool2.

While in theory this is possible, doing it for something other than HTTP will be much more difficult since HTTP already has a profile on the LTM to parse the payload very efficiently. To do it with a different protocol you are going to have to parse the TCP payload yourself via CLIENT_DATA event and you will have to use a oneconnect profile which may or many not work with your protocol https://support.f5.com/kb/en-us/solutions/public/7000/200/sol7208.html and https://devcentral.f5.com/wiki/iRules.CLIENT_DATA.ashx. If your key is very early in the payload and is consistent you can probably get away with only collecting a small amount of the payload.
