We have a rule in our firewall which prevents users accessing Facebook. If they try to do so in IE, they get the HTTP 403 message stating "The website declined to show this webpage". No problem with this.
However, many webpages have facebook 'like' icons, and other links to Facebook. When a user goes to one of these sites, generally the Facebook icon is replaced by the HTTP 403 webpage. See the attached document, showing EE with and without the Facebook block rule in place.
On the EE site, this isn't an issue as it seems to be contained in a frame (??? - I'm no web designer), but on some sites, you get this message in full, so it overlays the rest of the website making the content unreadable. It does tend to disappear after a few minutes, but it's still a bit of a pain.
Is there a way to supress this message?
If not, I assume I can edit it and remove the text? Although would this just leave me with whitespace covering the webpage rather than an error message covering it!
