Haproxy Wildcard regex in ACL

DXD

Is it possible to have custom acl like *.test.com
where it will work for :

test.com
test.test.com
test.test.test.com?

I read the documentation and a serverfault thread but none helped.
Any help will be appreciated.

Hi @DXD
Sorry been away for a week to two and still catching up.
Did you find an answer to this?
I think though (depending on what you are trying to do with the result) what you are looking for is hdr_dom(host) ACL rules

For example

frontend in
bind :80
acl is_domain1 hdr_dom(host) test.com
acl is_domain2 hdr_dom(host) test2.com
use backend domain1_svr if is_domain1
use backend domain2_svr if is_domain2

backend domain1_svr
server svr0 x.x.x.x check 80

backend domain2_svr
server svr0 x.x.x.x check 80

Again I'm guessing as you have not really said what you are trying to do.

Thanks bro for the heads up.

Will this work like
if i go to x.yz.test.com ?

It should do as I is only looking at the domain part but I do think that there is a path_beg or something along those lines.
I'm not at my full normal works machine at the moment so cant say for 100% and a Google didn't return what I was expecting.
If you also put in a 'default_backend' statement on your frontend configuration it should then catch anything that is not caught by an ACL rule.
If you still have issues getting what you want to work PM me a copy of your HAProxy config and details of what you are looking to do and I'll see if I can help.

I'd really just use hdr_end(host) -i .test.com

Thank you everyone.

@Zerpy hdr_end(host) nice spot that would do it perfectly I would think and @DXD your more than welcome even though I would think that @Zerpy answer would be a better option for what you are trying to do.
