First of all thanks for your reply.

No, unfortunately I don't have the machine nor the code at hand anymore, 
but I can tell you for sure that the same problem was happening both 
with IE and Firefox, and I was running the test server _without_ the -k 

Diabling the lan interface always solved the problem for both broswers, 
even without restarting mysapp_server.pl.
