    Hi Everyone

    I'm facing the below error when accessing a URL with 3 forward slash through iis reverse proxy.

    Sample URL : http://192.168.0.134/activity/documents.w3p;pioiid=dma%3A%2F%2F%2F45e6b900-8929-11d4-b772-0050da06bfb4%2F7bd350da-c9ee-4565-8000-2cbc18041961%2F%3Bguid%3Df2e18eef-35cd-4797-8a6d-54e8ab1d0147%3Bclass%3DProject

    can someone please help me to resolve this ? we cannot change the URL.

    Server Error in '/' Application.
