Servlet's request parameters

Hi,

I have a question regarding the reasons for using the getParameter method to retrieve both query parameters and HTML form parameters.

I have developed (and am currently revising) a Servlet like engine for Java, called Simple http://simpleweb.sourceforge.net/. I was wondering what the exact semantics of the HttpServletRequest.getParameter method were. For example is it

String formData = // get form data
String queryString = // get query string

String params = formData + "&" + queryString; // complete

This can be nessecary if there are duplicate parameters, is it typical to use the HttpUtils object and the HttpServletRequest.getQueryString method to clarify whether the parameter came from the request URI or the HTML form?

Thanks
Niall
