Hi,
Hi!
I want to write a simple component, which will say the number of users
online! But, to do, that i need to access the non-threaded version of
HttpServletRequest of the Tapestry servlet, how do i do that? Please help
me!
Some points:
1) Tapestry is a servlet filter, not a servlet.
2) There isn't a non-threaded version of HttpServletRequest, as it is
created for every request received.
3) As far as I know, it's not possible to count the number of concurrent
users without using the session, as HTTP is a stateless protocol. You'll
need to count open sessions. To do that, you'll need a service to hold the
number of open sesions and an HttpSessionListener.
I hope I gave you some pointers.
