Any thoughts?

Hi,
I am trying to set up a load balancer for a special binary protocol
which uses TCP for transport. Each TCP payload starts with sequence of
bytes which can be used for load balancing and stickiness. Each packet
starts with
4B ... protocol identifier FF00FF00
1B ... protocol version
4B ... ID which can be used for stickiness
4B ... metadata
Having this in mind I decided to define a binary stick-table
|stick-table type binary len 4 size 50 expire 2m|
and stick on derective
|stick on req.payload(5,4)|
When ID is 0 everything works, i.e., printing the stick table shows me
key=0000 and selected server, and all the communication is sticked to
the one selected server. However, when ID is not 0 I never get
stick-table entry and each TCP session goes to a different worker
according to the roundrobin.
I am afraid that it is some kind of a bug because I tried to use
string stick table as well without success. Example of a simple
communication is enclosed
Also, I can provide TCP server and client to generate this kind of
communication..
Thank you for help, Milos
