Right now it's just Apache. The only thing I have to go on is the httpd 
access log: - - [24/Jul/2007:19:59:54 -0400] "GET /gw/ HTTP/1.1" 302 - - - [24/Jul/2007:19:59:55 -0400] "GET 
/gw/login.php?cd=10&forward=%2Findex.php HTTP/1.1" 200 4742 - - [24/Jul/2007:20:00:50 -0400] "POST 
/gw/login.php?forward=%2Findex.php HTTP/1.1" 302 2 - - [24/Jul/2007:20:01:27 -0400] "GET /gw/index.php 
HTTP/1.1" 302 2

I just tried to login as another user and it delayed again. And when I 
try it directly to the real server I have the same effect so it must be 
something with apache. ... After some investigation I think this is an 
application problem. It is mainly just one application (the one I was 
testing of course) that appears to exhibit this behavior.

Rob, Bill,
Got no hits on the tcpdump.
On DNS: no DNS, everything is IP.
