Bad Request - Invalid URL HTTP Error 400の対処方法について。

routes.MapPageRoute を使用する場合、ルートの URL が 256 を超えると、記述のようなエラーになります。

回避策は以下の通りです。

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP\Parameters]
"UrlSegmentMaxLength"=dword:00000400
Open the registry above and add a new UrlSegmentMaxLength setting of 1024 length will basically satisfy most of your needs.
