Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: The channel does not stop reading the * * request data from a socket that has * * been set to close and waits until all * * the data is read * **************************************************************** * RECOMMENDATION: * **************************************************************** When the HTTP Channel is closing the connection (either at the end of a request/response or there was an exception during request processing) it will detect if all the request data has been read. If it has not, then the channel will attempt to read all the data from the socket so it can reuse the connection. This means that if there is a large amount of data left that the channel will have to read it all in, which could prevent other work from being executed in a timely manner. The channel has to read the data off the socket if it's going to leave the socket open to read for another request, otherwise it will read the stale data and encounter an exception.
Problem conclusion
The HTTP Channel will now prevent the request body from being purged off the wire if we detect it hasn't been fully read and the request is not persistent. A new custom property was added to the HTTP Channel to enable this new behavior. The property name is: "preventRequestBodyPurge" with a possible value of "true" or "false", with the default being "false". An HTTP Channel custom property can be set like this: http://www-01.ibm.com/support/knowledgecenter/SSAW57_8.0.0/com.i bm.websphere.nd.multiplatform.doc/info/ae/ae/rrun_chain_httpcust om.html?cp=SSAW57_8.0.0%2F3-16-5-416&lang=en Please note: the instructions are for v8.0, but the same instructions apply to all versions of WebSphere Application Server Full Profile. This custom property must be enabled if the Web Container Custom Property "com.ibm.ws.webcontainer.skipinputstreamreadonerror" is in use. If there is any exception during the process of the POST data, the Web Container property will stop reading in the remaining unread data. The fix for this APAR is currently targeted for inclusion in fix pack 8.5.5.4.
