Hi,

1. Is it possible to have proxy_pass be applicable to query_string variable
without using the location directive? I was not able to make this work in
the configuration file.

Specifically:

if ($query_string ~* "a=1") {
proxy_pass http://proxy1;
}

doesn't work unless its within a location directive

2. If the location directive is necessary then how do I make it get past
the location directive if query string doesn't match?

eg:

location ~ /foo {
if ($query_string ~* "a=1") {
proxy_pass http://proxy1;
}
}
If query string doesn't match I want to go further and check against
other location directives etc. How can that be done?


Thanks,
Ankur
