RE: Tomcat and Apache by Proxy http connections slow but https fast
Thanks for the help - problem solved! Was running a box with LVS, and running DNS. I don't think all the zone files were there, but stopping named worked like a charm - all webapps fast! What a stupid error (on my part). -Original Message- From: Tim Funk [mailto:[EMAIL PROTECTED] Sent: 18 August 2004 01:13 To: Tomcat Users List Subject: Re: Tomcat and Apache by Proxy http connections slow but https fast AFAIK - mod_proxy does not cache DNS lookups.

Sorry folks, more info (hope somebody will has experienced these problems as well!). I can hit 2 JSPs in different webapps, both proxied behind Apache, both on HTTP. The one is fast, the other slow.
