Need help in identifying a problem.

[achana chan]

Hi.
I have successfully implemented HTTP-tunnel, or so I thought, over the internal network. I managed to get to the web-page on the Apache server (port 80), then I got the applet to "tunnel" thru to the servlet and the servlet retrieved the data from the database. The data is flushed back and displayed on browser.

Then I tried to do the same thing from www.
Although I managed to get the web page, I could get through to Tomcat. The file catalina.logs register no such attempt. Therefore it stopped at Apache. Indeed , httpd's logs show that !
How to go about identifying the problem and debug it ?
