Struts Action + Multiple Request

[RODRIGUES DE ALMEIDA Thiago <TA...@brainsoft.fr>]

Hi All,
I have this scenario:

In my application, the user has the possibility of openning multiple
windows (browser) simutaneously.
In this case, each new window makes requests for data thru a struts
action.

That means, one user can make multiple requests to the servlet container
(Tomcat 5.5) at the "same time".

The problem i have is concerning the performance.
Since the user has oppened more than 4 windows, the browser (IE 6)
becomes freezed.

I have taken a look into the server and apparently there are no problems
of memory or processor.
For the Tomcat side, i did not see any disturbing problem concerning
performance.

What would you recommend as solutions for this kind of scenario ?

Thanks in advance,

Thiago de Almeida

No problem there, this is made for it and, unless you use something else
than request scope bean for your struts action, it shouldn't be a
problem for struts too.

Dump the Threads of your jvm, you might simply be in a deadlock with
your application.

If I am not wrong, this is a browser "bug" (or feature), not a Struts 
nor Tomcat issue.
If I remember correctly, both IE6 and Firefox open at most four 
connections to the same server and until one of them have finished, the 
other requests will wait.
