RODRIGUES DE ALMEIDA Thiago wrote: 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. 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. 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 ? Dump the Threads of your jvm, you might simply be in a deadlock with your application.

Hi Antonio, Thank you for your reply. Would you have the reference for these problems ? If it's a browser's bug or limitation, i would need to prove it. :) I'll try to do this research on my own too.

RE: [OT] Re: Struts Action + Multiple Request
Hi Antonio, Thank you for all these important informations. Now, one last point: What would you recommend for my scenario ? Should i limit the number of windows openned ? Or maybe should i try to pass over this HTTP limitation ? What would you do ?

Re: [OT] Re: Struts Action + Multiple Request
I love this part: ...you should avoid doing standard Web browsing while these settings are in effect Why should standard Web browsing not be subject to the HTTP Protocol Specification? These guys are characters. I'm glad I made the right decision years ago when I chose the Java camp, and not Microshaft.

RE: [OT] Re: Struts Action + Multiple Request
Thank you Antonio, I really need to figure out how to solve this problem. From the client's point of view, it's very annoying to have to wait for such a long response when he opens many browsers. Sometimes the main window, since the other windows open as popups, gets freezed. Well, if you have any other tip i will appreciate.
