/context1 is used just for directing users to the right application (or
context). Session is really maintained by /context2. Users can login directly
in /context2 or they can input username and
password in /context1 and they will be forwarded to the right context on of
which is /context2. So the login information could come to
/context2/Login.action via a direct POST to this action or via a
forwarded request from /context1.
The testing I have done is completely on /context2. Have some users login at
/context2/Login.action while JMeter tries to access /context2/Login.action and
another action /context2/PlanList.action
(requests to any action other than Login.action will get forwarded to
Login.action if the user is not yet logged in). So a direct request to
/context/PlanList.action will end up at /context2/Login.action.
I can't say that 2 percent of users were able to get in without
username/password. As I have ran the JMeter tests a lot of times (each run with
100 users). Only during one of those runs of JMeter I
had 2 requests get users home page when Login.action was requested (with out
username/password).
Below is the Login.action code. Removed the code that fetches the data for home
page.
Thanks,
