generally, "GET" requests, i.e. where name/values pairs are passed via the URL, take on the form:

http://subdomain.domain.tld:<port#>/myscript.cgi?arg1=val1&arg2=val2

You can skip the ":<port#>" part if you are using default httpd port 80. Also, characters like a space have to be written as '%20' like%20this%20here.
