Unexpected http parameter read using C#

Question

I'm not sure why am I getting such result.

If I load the following URL into a browser:

http://localhost:57845/app.ashx?n=update&url=some_url&logo=long_logo_name

where the app.ashx file contains this code:

public void ProcessRequest(HttpContext context)
{
    string strURL = context.Request.Params["url"];
}

My strURL variable becomes some_url,/app.ashx. Any idea why?

This is because the Params property "gets a combined collection of QueryString, Form, Cookies, and ServerVariables items" (see http://msdn.microsoft.com/en-us/library/system.web.httprequest.params.aspx).

You should use context.Request.QueryString["url"] to get only "some_url".
