REST call problem

[devboycpp]

In my local machine in my web site. I have a url mapper http module in place which maps a url like 2013/09/pid/productname.html/webpagemethod to product.aspx/webpagemethod?id=pid&y=2013&m=09&name=productname What I'm trying to do is invoking the webpage method via REST method. I have included ScriptHandlerModule in httpmodules section of the web.config file. The call to the webpage method from the javascript fails in my local machine with error saying "this method is not allowed" but succeeds when is run from the deployment machine. The only difference between the local and deployment machine is the former is IIS6 and the latter is IIS7.5 in integrated pipeline mode. Does anybody know the cause? Should query string parameters be included in a REST request at all? Thanks in advance
