Hi,
I am become crazy!
My wicket web application works fine on my laptop on localhost,
but don't work well on my home server.
I made all the web site stateless. I don't need user login. But one page is
stasefull because
I use wicket Ajax Tab Panel. On this page I have youtube video, with some
panels that give informations
about the selected video, taken from youtube API using java. The first panel
give information like title, author, views, ecc.
The second panel give comments of that video, ecc.
My problem is that when user pass from first panel to second panel, the
comments returned is related to another video!
When come back to first panel the information changes and it is relative to
another video too!
It looks totally random! But I think that the information on the actual panel
is related to video selected by another user connected to my web site.
I known that there are user connected to my server every second, just because I
can see upload bandwith used by system information graphic, and I
know by Google Analytics that every day I have about 500 users connected.
Infact when I test the application on my laptop on localhost it works well, all
things is ok, and I am the only user of course.
How can I do some check to understand well the problem?
How can I solve the problem?
In my application I don't manage the Session, because I don't need, and I know
that wicket automatically create a Session, infact
on ajax page I can see jsession=xxxxx in the url.
How can I know more instant informations about how many users connected and
what pages that users are wacthing now?
I use wicket 6.2.0, Tomcat 6.2.4, Eclipse EE, Linux, Home server and ADSL
