Now done!
Quite happy to see this done with. Any issues can be addressed as bug
fixes.
Yes, same here. I've updated the ROADMAP file to remove this 8-years
old entry :-)
Great ;-)
As we now have this feature, Patrick do you plan to create a blog post
or a example config for this new feature?
Sorry to say this but I haven't understand this feature fully.
I was going through the discussion and there are some mentions about
time based and a example with date.
I have found some informations about "load balancer priority based" but
I'm not sure if this matches the implementation in haproxy.

Let me explain how I understand this feature and you can fix my gabs for
this feature.
I think it is a requeue mechanism for the connection and not a selector
for a server or a backend, but I can be wrong.
###
listen|frontend test001
bind :8080
# some other options
http-request set-priority-class -10s if PAY_BUTTON
http-request set-priority-offset 5s if LOGO
http-request set-priority-offset 5s if LOGO
# as a sample expression can also be this, right?
http-request set-priority-class \
%[req.fhdr(User-Agent),51d.single(DeviceType,IsMobile,IsTablet)]
# could this work ?
use_backend high_priority if priority-class > 5
###
The set-priority-offset is for separate the *same* classes in more
pieces right.
request 500 -> class -4 -> set-priority-offset 0
request 600 -> class -4 -> offset -3
request 600 will be delivered before 500 right?
I'm also willing to write such a blog post as soon as I have understood
the feature ;-), similar to spoe feature.
