Hello,
I am hoping someone can assist me with a problem I am experience, in what I think is originating from Glassfish 3.1.2.2, or maybe a bad combination of a behavior in GF and Internet Explorer 9.
I have deployed a Java EE app, which runs a JavaScript timer on the web-browser to poll the server (servlet in glassfish) via an ajax call to simply check for server availability. Throughout the day, this poll will fail in a very unusual way: the HTTP body will be empty when it shouldn't be. The poll operation makes this problem most visible, but often other, less visible, async operations will fail too.
We've done a pretty thorough investigation and discovered that IE probably has a defect which is causing this problem, but at the same time I can't imagine GF behaving in this way to make IE exhibit it's defect. From my examinations, everything works fine until IE attempts to make an HTTP request on a keep-alive connection and receives a TCP RST instead. IE will then re-establish the TCP/HTTP connection, but will only send the HTTP headers. GF waits 300 seconds to receive the HTTP Body, never does; finally GF then sends what it has for the HTTP request through the server stack to the servlet.
I've attempted to disable HTTP keep-alive by setting the Max HTTP keep-alive connections to 1. This appears to have helped, but it does not eliminate the problem. Plus I would prefer to not disable keep-alive.
Given the prevalence of Internet Explorer, I can't imagine GF is exhibiting this problem for other company's else I'd have seen more reports of it on the internet. I am suspecting it's a configuration issue, but I can't pinpoint what I need to change. We've tried various configuration tweaks with no luck. Any ideas?
Thanks
-Sean
