[users@httpd] mod_proxy_balancer / mod_proxy_http question - stick tables support
based on url
Hi all,
I've got a question about:
https://httpd.apache.org/docs/2.4/mod/mod_proxy_http.html
and
https://httpd.apache.org/docs/2.4/mod/mod_proxy_balancer.html
Can balancing of apache httpd be configured to use stick tables to
balance requests (having HAProxy in mind)?
With HAProxy you could define something like:
stick-table type string len 256 size 1M expire 1h
stick on path,field(3,/) table mytable
I want to balance requests with httpd based on a part of the URL (no
cookies there) (/r/${balancePart}/...) and it should balance that in a
way that there are some preferred rules like:
balancePart in (1,2,3,4,5) -> use Server A,B,C,D
balancePart in (6,7) -> use Server E,F
balancePart in (other) -> use Server E,F,H
Nevertheless if some of the destinations are failing - it should fall
back to whatever destination is still there.
Can this be achieved with httpd at all - if so, how?
If not all of those requirements are possible - what would be the best
I could achieve with mod_proxy_balancer + mod_proxy_http?
thanks and kind regards
Torsten
