I am using squid for an internal proxy for our network. On occasion, I have had issues where squid throws back a blank page 2-3 times before finally loading. One especially apparent time for this is when logging into facebook. The relevant parts of the squid configuration are below (everything else is all ACL related).

maximum_object_size 100240 KB
maximum_object_size_in_memory 5 MB

# Trying to fix blank pages...
forward_timeout 1 minutes
connect_timeout 30 seconds
negative_ttl 0 minutes    
positive_dns_ttl 10 seconds
negative_dns_ttl 10 seconds
dns_nameservers 4.2.2.1 4.2.2.2
forwarded_for off

Any ideas as to what I could change around to avoid hitting blank pages would be greatly appreciated.

If you are using it internally shouldnt you be using internal DNS servers not external DNS 4.2.2.1 4.2.2.2? Or have I misunderstood your question? The reason I say this is that I had a similar problem with DNS that produced a similar output.

The root DNS servers are in there because I was trying to determine if it was a nameserver issue. I've switched them back to use the internal DNS servers, thanks for pointing that out (I forgot I had that in there). It does not solve the problem though. – Michael Oct 28 '09 at 12:30
