ClientAbortException - when do multiple request at same time
Joined: Sep 23, 2008
When i do simultaneous http request(monkey clicks) is made on the web application i am getting following exception like
Jul 9, 2012 11:05:23 PM org.apache.catalina.core.StandardContextValve throwable
WARNING: Exception Processing ErrorPage[exceptionType=org.apache.jasper.JasperException, location=/jsp/content/utils/error.jsp]
ClientAbortException: java.net.SocketException: Broken pipe
Cause : The warning log basically means that the connection to the client browser is aborted before the response is fully transferred. It is a harmless warning as it can be due to transient network problems or the browser aborts/refreshes the page before it loaded.
Is there any specific configuration in tomcat(sever side) to solve the problem? Please help me
To my point of view am understanding that you are trying to send multiple requests on a shared resource. In such case You have to make the servlets synchronized , So try to synchronize your threads before sending it to container.
Hey! I am not a monkey! I just have spastic fingers. Also a jumpy nerve in my shoulder that can do a lot worse than just double-click, alas!
HTTP requests are serviced asynchronously and independently. There's no real way for the webapp server to objectively determine whether those 2 overlapping requests are legitimate or not. In fact, the requests won't even overlap initially, since (usually!) one comes in first, then the "monkey click" arrives a few milliseconds afterwards.
You can safely ignore the error message, and as I said, it's not really anything you can do anything about.
On the other hand, the application should be making allowances for possibly servicing the request twice, because that could potentially cause trouble. Especially when payments are being made.
The usual way of "handling" that is to warn people no to click more than once, but that's lazy and sloppy and doesn't take into account that people have been conditioned to double-click to do things or that they may have hair-trigger reflexes, like me.
Customer surveys are for companies who didn't pay proper attention to begin with.

Thanks for your reply. ... My thought is request is committed while flush the response i made another one request. Even though i synchronize the request(queue the request), while render the response i am getting exception. Typical example is session, I am have different context with same session id. When i do many click in different context session id is same but session values is getting changed.
