我写了这个测试，一直在添加'a'参数，直到浏览器失败
C＃部分：
[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();
}
视图：
$(function() {
var text = "a";
for (var i = 0; i < parseInt(@ViewBag.TestLength)-1; i++) {
text += "a";
}
document.location.href = "http://localhost:50766/Home/ParamTest?x=" + text;
});

在Chrome上，我得到了：
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.130 Safari/537.36
2046
然后爆炸：
HTTP错误404.15 - 未找到请求筛选模块配置为拒绝查询字符串太长的请求。
Internet Explorer 8和Firefox上也一样

我进入了简易模式并为IISExpress applicationhost.config和web.config设置添加了额外的限制maxQueryStringLength="32768"。
Chrome failed with message 'Bad Request - Request Too Long
HTTP Error 400. The size of the request headers is too long.
在7744个字符之后。
Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.130 Safari/537.36

这根本没有帮助。我最终决定使用fiddler从头文件中删除引用者。
static function OnBeforeRequest(oSession: Session) {
if (oSession.url.Contains("localhost:50766")) {
oSession.RequestHeaders.Remove("Referer");
}
哪个做得很好。
Chrome：得到15613个字符。(我猜这是IIS的16K限制)
它又失败了：
Bad Request - Request Too Long
HTTP Error 400. The size of the request headers is too long.
