2 variables inside if() ?

[untamed]

Hello,

I'm trying to compare 2 variables, like so (I've made sure the variables
match):

[code]if ($arg_hash !~ $sha1) {
...
}[/code]

However in error.log it says:
[code]*1 "$sha1" does not match
"a78c3ecd2e349d1f1050fa555842a60b585489d8"[/code]

I've tried swapping the variables over and the same error occurs, so it
looks like the variable after the comparison character(s) is considered
a string by nginx.

Does anyone know of a way to do this? Or of a third party module which
does this?

Thanks very much.
