[NTLUG:Discuss] ot- first user take longtimetocompleteloadwebpage.

Tue Nov 25 16:54:42 CST 2003

Harsha and all:

Thanks to you all. The problem was solved.
The porblem is the firewall set the http connection (actually all 
connections) will be disconnected after  idle for 30 minutes.
the applications have service brokers connected between firewall, when the 
firewall disconnected all connections and the existing service brokers' 
session 'did not know' it. these 2 service brokers still trying to connect 
till time out. that is why take so long to logon the complete webpage.

thanks you all a lot.
