Hello,
we enabled the https inspection, but when a users surfs to a site which don’t have a valid certificate (self-signed) there is only the default Web-Browser error
message, that the site isn’t reachable.
In the TMG Log is the reason 12226 noted, that’s OK, but we’d like that the Errormessage from the Errorhtml 12226.htm is shown to the User, that he knows
why the access is blocked.
--edit--
just found out that it works with Internet Explorer 7 but not with 8 or Firefox (3.6.3). Always the default browser Error-Pages (502 Proxy Error) are shown and not the TMG Error-Page.
Thanks
