RE: [squid-users] Transparent proxy - some pages show up blank

I'm from the other end of the spectrum. I prefer autoconfiguration files
to transparent proxies. And, interestingly, for the same reason: they're
easier to maintain and support. :-)

I suspect one's preference depends on the security policies that one has
to address: DoD, DND, MoD, etc. environments tend to be more restrictive
and autoconfiguration files seem to work better in these environments.
