i have setup an http advanced sensor, and this sensor states reponse must include "Forbidden". response must not include "string of web interface login page". this web interface is not accessible via prtg, which is correct, as it is only available to certain ip addresses. we want to monitor for the default apache 403 forbidden error page to ensure that the restriction is still in place, however the sensor stays in error state, although the apache forbidden page does come up when browsing to the web interface url.
able to monitor http response 403?
