Hello,

I have some location in configuration like this:  
location ~ /([A-z]+\_[A-z0-9]+) {  
… do something (got $1) …  
}

And i need to compare this ‘$1’ with a set of strings. How can i do  
this?

Thanks!

Use a named capture in the location line and the resulting variable  
won’t get clobbered like a $1 would.
