Stuck...Simple iRule? Not sure...req for Help

Hamish;

 

 

I believe the length of the data in packet we are looking at is 281 bytes. I thought I saw code somewhere to allow you to specify length. I don't think the data is textual, probably binary, not that i know for sure, i am using wireshark and can search through the packet to find the AETitle i would expect embedded in the packet always at the same spot 0040 of the conversation. Does that make sense? Not sure about using a stream, i am more than happy to learn more so i will take a look ath the proxy pass irule, can we still do that if the data is not textual?
