How do you access HTTP GET parameters in Nginx prior to version 0.7.8?

Question

The changelog lists version 0.7.8 as the version that introduces the $arg_X notation to access the HTTP GET parameter X from within nginx.conf.

Unfortunately, the wiki is very up to date. How do you access HTTP GET parameters from within nginx.conf before this version?

Answer 1

At the moment, the best I have is matching against $args.

For instance, instead of saying if ($arg_user = "jim") you can say if ($args = "user=jim"). This particular example only works for a single argument, since multiple arguments can come in any order; that case should be handled with regular expressions.
