Getting error "potentially dangerous Request.Form value" on ASP Page on Windows Server 2019
IIS and ASP.net problem.
I have an application that I recently moved from Windows Server 2008 to Windows Server 2019.
Some of the data being saved contains </=, which produces an error: A potentially dangerous Request.Form value was detected from the client
My page header contains:
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="WaferRFP.aspx.vb
I have also tried adding:
<pages validateRequest="false"></
to the System.web section of the Web.config file, but I am still getting the error message.
What am I missing?

Hi Yonbert,
I think you would want to approach it from two sides
1. Try encoding the form values before submission.
2. Try setting the validation mode to backward compatibility
If you try the 2nd point, I would recommend doing it only for the pages where you are facing this error.
