Hi everybody
I have an application that uses servlets as fronted, and one of its
main requirements is to be highly scalable, so I want to be able to
split
my app servlets between several web servers. My app uses the Session API
to keep track of the user events, so I need to have a way that if a user
first hits in a webserver and then in another webserver the servlet in
the new webserver can access the session info of the first one.
As long as I can think of I see the next two ways to handle this:
a) Get (Buy or Program) a web balancer device that is smart enough
to get some session info from every request, so it can redirect all the
request from a user to the same webserver. Do you know of some similar
device?
b) Have a servlet engine that has support to share session across
several webservers, this could be implemented through a shared database.
I would prefer just to buy a product like this, but if not I'd suppose
I'll to program it.
Is there any other choice that I'm missing?
Thanks in advance for your time.
bye
andres
