The string(in this case, 'db=default&uid=default') after ? in a URL is called QUERYSTRING. This is one of the methods(called GET method, other is POST) of passing informatiion from your browser to the server. In a CGI script you can collect this string in a variable named QUERY_STRING(or may be QUERYSTRING). An & in this string seperates various key-value pairs(in this case there are two key-value pairs). Once you read this in your CGI you can parse the string and respond accordingly. Generally this method is used when you've to send small amount of information. If the data to send is more POST method is used.
