Vulnerability : "WebDAV extensions are enabled"" : Suggestion Needed

Hi again - the above will ensure that WebDav functionality works, however if what you are trying to do is to remove the vulnerability and disable WebDav, then you will want to block any WebDav requests;-

when HTTP_REQUEST {
    switch [HTTP::method] {
        "GET" -
        "POST" -
        "HEAD" {
             Allowed methods - do nothing
        }
        default {
            HTTP::respond 405 content "Method not allowed"
            return
        }
    }
}

This will mean that wehn you re-run your scan you will not get pinged on WebDav (but obviously this depends on your business requirement).
