Description

Hey there, dear nginx team.

Normally, $arg_paramname should hold the value of paramname in uri of GET request. But, when paramname comes right after "?" (i.e. GET host.com/page?paramname=1), $arg_paramname is not set to 1. Whereas, if paramname does not come right after the "?" (i.e. GET host.com/page?otherparam=2paramname=1) $arg_paramname is set properly.

Works fine here. Test configuration:

server {
    listen 8080;
    return 200 "$arg_paramname\n";
}

Testing it with simple HTTP request:

$ telnet 127.0.0.1 8080
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
GET /page?paramname=1 HTTP/1.0

If you see a different behaviour, please provide a reproducible test case.
