I'm getting a "The request Url has wrong character" warning when I attempt to save this valid format on the Request URL:
baseball/index1.aspx?team=Arizona+Diamondbacks
Also, having a classic ASP page on the request does not seem to work. Try adding baseball/index.asp on the Request Url and redirect it to any nop page. The plugin will save the record, but when you test it - the page get's a 404. This could be an IIS setup issue and not necessarily nop.
