Page not found the first time client accesses it, all other times OK

[Alexander Telnikoff <at...@red-oct.u-net.com>]

I have this strange behaviour under Apache/Tomcat: the first time a new
browser tries to open a URL (a frameset pointing to a servlet), HTTP
response is not sent back and you get "Page not found or DNS error". If user
refreshes the page, everything works normally.

This behaviour is only evident when Tomcat is running. All non-servlets work
fine when served through Apache when tomcat is shut down. Has anybody
experienced a similar problem?
