>Regards, >Eliezer Thanks for the reply and further clarification, I still believe the issue I am reporting is specific to DNS and how Squid's internal DNS resolver works. I forgot to mention if I bypass using the hostname in my test, and enter one of the resolved IP's instead of webapps.kattenlaw.com it is immediate. There is no delay in bringing the page up. I also tried another variation while testing today, I re-compiled Squid 3.2.9 with --disable-internal-dns and it has different behavior indicating even further that the problem lies within the internal resolver Squid 3.x uses. When 3.2.9 is compiled with --disable-internal-dns, the first time I access webapps.kattenlaw.com it only takes 15 seconds to come up instead of 30 it took while having the default 3.2.9 internal resolver functioning. Then subsequent connection attempts to https://webapps.kattenlaw.com come up instantaneously every time after that. (Switching between different browsers using the 3.2.9 as the proxy server) Indicating the name is cached at that point and not re-queried on my 3.2.9 box. In all my reading I think I recall reading somewhere that when using external DNS resolution with squid that it can wind up ignoring TTL on records. In this case the record TTL is only 5 seconds right now, so I know it is ignoring the TTL. If I restart squid, it will take 15 seconds to resolve it the 1st time. =========================================================== CIRCULAR 230 DISCLOSURE: Pursuant to Regulations Governing Practice Before the Internal Revenue Service, any tax advice contained herein is not intended or written to be used and cannot be used by a taxpayer for the purpose of avoiding tax penalties that may be imposed on the taxpayer. =========================================================== CONFIDENTIALITY NOTICE: This electronic mail message and any attached files contain information intended for the exclusive use of the individual or entity to whom it is addressed and may contain information that is proprietary, privileged, confidential and/or exempt from disclosure under applicable law.
