AW: use_backend: brackets/grouping not accepted in condition
Hi Baptiste,
it is IMHO not really clear that brackets are for anonymous ACLs only.
Wouldn't it make sense to support it for use_backend as well?
It just makes things easier in my opinion.

Hi Christian,
Brackets are for anonymous ACLs only.
You seem to use named ACLs with brackets so it can't work.
Either you do as you said:
use_backend backend_test if request_domain1 allowed_ip_foo or
request_domain1 allowed_ip_bar
Or with 2 use_backend:
use_backend backend_test if request_domain1 allowed_ip_foo
use_backend backend_test if request_domain1 allowed_ip_bar

Hi Guys,
I just tried to simplify some rules and I noticed that brackets {} doesn't
work
with use_backend while it works fine with default_backend.
That doesn't work:
use_backend backend_test if request_domain1 { allowed_ip_foo or
allowed_ip_bar }
That works:
use_backend backend_test if request_domain1 allowed_ip_foo or
request_domain1 allowed_ip_bar
That works as well:
default_backend backend_main if request_domain2 { allowed_ip_foo or
allowed_ip_bar }
I could also use multiple use_backend's but using brackets would make it a
lot easier and better readable IMHO.

That also sounds like the brackets should work almost everywhere.
Some actions are only performed upon a valid condition. A condition is a
combination of ACLs with operators. 3 operators are supported :
- AND (implicit)
- OR (explicit with the or keyword or the || operator)
- Negation with the exclamation mark (!)
A condition is formed as a disjunctive form:
[!]acl1 [!]acl2 ... [!]acln { or [!]acl1 [!]acl2 ... [!]acln } ...
Such conditions are generally used after an if or unless statement,
indicating when the condition will trigger the action.
I would really like to see that fixed. Or is that on purpose?

Those two are not mutually exclusive: you can use them with use_backend and
they are for anonymous acls.
for example:
use_backend www if METH_POST or {path_beg /static /images /img /css}

AW: use_backend: brackets/grouping not accepted in condition
Hi Bryan,
I am somewhat confused now..
So it sounds like the behavior of the brackets in combination with
default_backend is wrong since it seems to work fine there even with IP ACLs.
And what I meant is, wouldn’t it make sense to support e.g. IP ACLs with either
{} or () or whatever else to allow one to group the rules instead of writing
multiple use_backend lines?
For small stuff, like in my example, it would make it slightly “easier”.
use_backend if somecondition (foo or bar)
vs.
use_backend if someconditoon foo
use_backend if someconditoon bar
