Subject Repost:Pl. help!!: Identical session IDs in Netscape 4.7, for different sessions
Date Fri, 14 Jul 2000 10:35:58 GMT
Hi people,

sorry for taking up bandwidth, and also apologies for the duplicate post(for 
those of you on both the general and the tomcat-user list), but i'm stuck 
with this problem here. I tried searching the tomcat-user archive for any 
solutions, but couldn't find any. any help will be much, much appreciated.


 >i just noticed a strange behaviour on netscape 4.7 on NT4.0. i'm >trying 
to use the tomcat-generated session ID to identify netscape >browser 
sessions. what i noticed is that the first time i go to my >site, a 
sessionID is generated and sent back as a cookie(by the >session-tracking 
API). now if i open a new browser window, the *same* >sessionID is sent back 
from the browser, and used  by the servlet >engine. so if i use only the 
sessionID to track sessions, there is no >way to distinguish between two

behaviour is probably due to the >fact that there is only one netscape

process. Here are my questions:
