如何显示AJAX HTTP请求收到的QueryString

Question

We have a script A which pulls information by sending an HTTPRequest to script B, with some GET parameters.

var URL = "http://domain.com/scriptB?ID="+ID;
var XMLGateway = new ActiveXObject("WinHttp.WinHttpRequest.5.1");
    XMLGateway.open("GET", URL, false);
    XMLGateway.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

This script B then uses an ID in the querystring passed to it to return some information. However this is inconsistently throwing errors.

Some investigation shows instead of the ID we're passing in the GET (which always takes the format of a five digit number), it is using a string like ".sp-app-5" where the number has been 5-9 so far.

String("["+Request("ID")+"]"); // [.sp-app-9]

I'm having trouble dealing with this bug as Request.QueryString used in script B is showing the QS that script A receives. However, Request("ID") is returning the unusual string as above.

Server.HTMLEncode(Request.ServerVariables("HTTP_HOST")); // domain.com
Server.HTMLEncode(Request.ServerVariables("QUERY_STRING")); // scriptA?some=values&foo=bar (same result as Request.QueryString)

How can I show the querystring that script B is receiving in the HTTP Request?

If I understand correctly, you need to verify that Script A is sending the GET Querystring in the request correctly. For situations like this I often use a free tool called "Fiddler" from Telerek (on windows). It will watch all your http calls and log the request and response, including the query string. Its pretty easy to install and is very useful when doing this type of project.

This will help you narrow down if script A is sending the ID correctly, or if Script B is interpreting the ID incorrectly.

Hope this helps!
