haproxy match various conditions in use_backend

Question

I'm trying to match various conditions inside one backend, like this:

acl rule1 hdr_dom(host) -i ext1
acl rule2 utl_beg /img
default_backend back-server-http if rule1 and rule2

but, how can I put this "and" between the two rules?

Answer 1

Yes, this is the solution:

acl rule1  hdr_dom(host) -i www.uno.es  hdr_dom(host) -i www.one.com
use_backend uno.com if rule1

How can a request have both hosts? It seems impossible that this ACL could ever be matched. – Molybdenous

Yes, you can, its the same if you add contidions to the same acl inside different lines. – Continuum

the answer example doesn't match the question example: for the question would it be something like this: acl rule1 hdr_dom(host) -i ext1 utl_beg /img? – Moise

@Moise - see the examples here: github.com/langpavel/haproxy-doc/blob/master/version-1-4-19/tex/…. Given what you've written I'd expect that to work. – Grigg

Answer 2

You don't need to use the word "and" between the two rules. It's implicit.

I think the below syntax will do the trick (check this link HAProxy - basic authentication for backend server)

acl rule1 hdr_dom(host) -i ext1
acl rule2 utl_beg /img
default_backend back-server-http if rule1  rule2

'default_backend' cannot handle unexpected argument 'if'. – Essam
