We want to block a URL containing a /%2F in it, like: http://www.example.com/%2Fblockme
However, when we add /%2F into BadURLChars ACO parameter list, nothing happens. We have the parameter configured as follows:
Also, if we add %2F into BadURLChars list (without the slash), agent function will break and we get an HTTP error 500 from agent.
As this is not blocked, browser is getting a HTTP 404 error which we do not want to show for security.
