Thanks :-)
Ok, I almost got it... The backend stuff and the errorfile trick is working,
but I'm having a few problems with the content switching rule. So here's the
backend stuff:
backend options
server vm-host01 127.0.0.1:8081 maxconn 50 disabled
errorfile 503 /tmp/resp.txt
At first I tried this rule:
acl req_options METH_OPTIONS path_beg /url1
use_backend options if req_options
But that doesn't pass the configuration parser:
[ALERT] 095/124538 (2706) : parsing [/etc/haproxy.conf:41] : error detected
while parsing ACL 'req_options'.
[ALERT] 095/124538 (2706) : parsing [/etc/haproxy.conf:56] : error detected
while parsing switching rule.
[ALERT] 095/124538 (2706) : Error(s) found in configuration file :
/etc/haproxy.conf
[ALERT] 095/124538 (2706) : Fatal errors found in configuration.
So then I tried:
acl req_options path_beg /url1 METH_OPTIONS
use_backend options if req_options
And the parser sees no errors, but of course the METH_OPTIONS implicit AND
isn't really working. How can get, in that same ACL rule, the OPTIONS method
and the specific /url1 both matched?
Thanks so much.
Pedro.
