RE: [squid-users] Issue related to using Squid 3.1 or 3.29 and accessing a site that uses a recursive DNS record. (30 seconds to bring up site)

I just wanted to follow up on this one last time.

I found with the timeout set low, it still would cause problems with certain browsers like IE, where the page would reset and the intended page would not display after the 5 seconds I had it set to. (on a DNS lookup for an AAAA record)

I recompiled Squid with --disable-ipv6, and then that seemed to work the best. I did not need to lower the lookup time then. And it works fast every time.

I would assume this same problem would occur with any DNS that does not provide ipv6 AAAA record.
