I did try even that..
Interesting thing happens when I set tcp-inspect delay to 10s, my
stickiness rule appears after 30s. The problem is it takes very much of
time, and the stickiness then actually does not work, i.e., I can see
that every further response goes from different server. Also, the
stickiness rule does not appear everytime, only exceptionally..
My stickiness rules goes from first packet hence only a few ms should be
OK, but it does not work with such a short time at all..

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
Hi,
Did you use tcp-inspect delay, without this parameter you do not have the
warranty that data is available in the buffer (see example of
https://cbonte.github.io/haproxy-dconv/configuration-1.5.html#4.2-stick%20store-response).
