The current English error message text that I see from
our error message system became overkill, with all those nice designs and multiple
in certain cases serving that message too certain requests caused gigabits of bandwidth.
it is also not practical to update it with policies, because, um, it has all those nice
designs and multiple languages.
we may actually end up having better error messages at some point in the future.
Everything except the very last line of that is either
wrong. And ERR_ACCESS_DENIED, though vaguely informative, provides no
detail about what happened or how to do things properly.
This is bad enough for bot operators who are likely to
intelligent people, but if we are going to give this to everyone with
a missing user agent string too (which includes people behind poorly
behaved proxies and people who use certain anonminizing software out
of intense desire for "privacy"), then this kind of response really
starts to send the wrong message.
We're not sending this response to missing UAs, as this response is being sent by
Squid ACLs, and the UA check is done at the MW side.
