![]() APAR status Closed as program error. Error description A significant amount of CPU time is spent in method Http_Request_Parser::processCookies. This is a bug in the HTTP Transport, such that it parses the request headers looking for cookies, when it already has determined there are none. The method should just check for cookies, and finding none, should return, instead of parsing all the headers looking for session data.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: Performance degradation can be * * experienced for requests over the HTTP * * Transport. * **************************************************************** * RECOMMENDATION: * **************************************************************** HTTP requests take excessive cycles in the HTTP_Request_Parser::processCookies method in the Control Region while parsing and handling HTTP requests that do not have any cookies.Problem conclusion A check was added to not search for the session cookie on HTTP requests when there was no cookie header at all.
