Frontend priorization

Help!
1

Hi

Is it possible to prioritize a tcp frontend over an other with same or overlapping backend?

Our use-case: I have a priority and a normal tcp frontend with same config and backend servers. Now I have to make sure that the priority frontend will always be prioritized in the queue. Is there a nice solution without separation of the backends?

I assume you can use queue priority classes, as per:

http://docs.haproxy.org/2.0/configuration.html#4.2-http-request%20set-priority-class

frontend prio1
 bind :100
 http-request set-priority-class int(-1000)
 default_backend back

frontend prio2
 bind :101
 http-request set-priority-class int(-500)
 default_backend back

frontend prioDef
 bind :102
 default_backend back

My requests aren’t http. I didn’t see the same option for tcp mode.

According to the docs, it should be compatible with tcp-request content:

tcp-request content set-priority-class int(-1000)
