There has been such a request for a long time, when it was not possible at all. Right now it's much easier to implement, since we're already able to perform TCP content analysis if we know what we're analysing (eg: SSL, RDP, HTTP, ...). So basically we're just missing the ability to match raw strings, which should be easier what is currently performed. Do you think that pure string matching would be OK to select a server, or do you need something such as extracting the customer ID and hashing it for load balancing ? It's not the same thing, because in order to perform load balancing, we have to define how to extract the data to be hashed, which is more complex than pure string matching. Regards, Willy
