That is true; but there other viewpoints to address this issue :
- at our company the SQUID proxy must be used , else people
can have no web access.
- we use a commercial tool to install PC's (over 2000 installed
base) where user get's various
applications either under Linux or Windows. We can package browser(s)
so that the proxy settings are already correct.
So user's don't know anything, about these issue(s), and are happy;except
when they try to be smart and change the browser proxy setting; and then
they loose Web access on our Intranet... Doesn't happen very often,as you might
guess.
