URLConnection timeout in JDK 1.0.2

I am calling URL's from my applet with some specified parameters, this URL then performs a query against a database.  These queries can take anywhere from seconds to an hour.  With the longer queries, java receives an IOException after about 10 minutes of waiting.  Is there any way around this behavior?

Also, when I try to recover from this IOException, the next call to the web server isn't accepted.  Is this because these two requests are in the same thread and it thinks the other connection is still open?  The other connection shouldn't still be open though, as I call my closing method in the finally block after I catch the first IOException.

Any help would be appreciated.  Thanks.

I don't believe that you can change this behavior.  At least not in your Java application.  I think you are running into an underlying operating system timeout that is eventually getting back to Java as an error.  How about another suggestion?  Instead of just having the connection sit idle while your query processes, how about sending back a progress update every so often?  Not only would this keep the time-out from happening, it might pacify your savage user who doesn't know why the darned thing is taking so long.

So, if I was to send back some sort of progress indicator, the OS would think that the connection was still alive, and keep it open?  Or does would it close it after 10 minutes anyway, just because it doesn't like to have HTTP requests open for more than 10 minutes?

Do you have any idea why the web server wouldn't accept another request while the initial page was being processed?
