How to create a Policy to block websites

There is a "how to format" link on the top right corner...

I don't see any error on the code:

when HTTP_REQUEST {
    if { [HTTP::uri] equals "/owa" } {
        HTTP::respond 301 Location "https://mynewurl.co.uk"
    } elseif { [ class match [string tolower [HTTP::uri]] contains web-exchange-external-datagroup ] } {
        return
    } else { drop}
}

But in your first request, you wanted to do it with a policy...

you can create a local traffic policy to do the same:

• requires : http
• controls : forwarding
• Strategy : first-match
• rule 1:
  • condition : http-uri path starts_with /owa
  • action : http-reply redirect Location : "https://mynewurl.co.uk"
• rule 2:
  • condition : http-uri path starts_with /autodiscovery /etc ...
  • action : none
• rule 3:
  • condition : none
  • action : forward reset
