Hello everyone,
I have a strange issue. On very rare occasions I get the wrong
information out of my JSP pages. What I mean is when a request comes in
I get the information that is stored in a different session. I have
tried bombarding the server to see if it is a threading issue and can't
seem to repeat it. All of my variables are either session values or
local to the request so it shouldn't be a threading issue anyway. Has
any one else seen this? I have included the JSP source below. It is
protected via login using the 2.2 security model. If anyone needs more
info let me know.
Thank you in advance,
Chris Heinemann
