Answer 1

I wrote this test that keeps on adding 'a' to parameter until browser fails

C# part:

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult ParamTest(string x)
{
    ViewBag.TestLength = 0;
    if (!string.IsNullOrEmpty(x))
    {
        System.IO.File.WriteAllLines("c:/result.txt", 
                       new[] {Request.UserAgent, x.Length.ToString()});
        ViewBag.TestLength = x.Length + 1;
    }

    return View();
}

View:

I added additional limits to IISExpress applicationhost.config and web.config setting maxQueryStringLength="32768".

also Added to config

which didn't help at all, Finally decided to use fiddler to remove referer from header.

static function OnBeforeRequest(oSession: Session) {
if (oSession.url.Contains("localhost:50766")) {
        oSession.RequestHeaders.Remove("Referer");
        }

Which did nicely.

On IE9 I got

Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
