While working with the `http-request set-var` (and a few other places, but primarily here), it would be very useful to be able to use haproxy format strings to define the variable.
For example http-request set-var(txn.foo) fmt(%ci:%cp:%Ts) Or even http-request set-var(txn.foo) fmt(%ci:%cp:%Ts),crc32() I don't currently see a way to do this, but I could be missing something. If it's not possible, any chance of getting it added? -Patrick
