Thanks, Dustin Tomcat recycles HttpServletRequest objects. If an application retains a reference to a request then you can see the behaviour you describe. Setting the following system property: org.apache.catalina.connector.RECYCLE_FACADES=true will cause Tomcat to create a new wrapper for each request/response. This has two advantages. One it should stop one request seeing data from another. Two it should trigger an NPE when the application tries to access to request/response that has been retained after it should have been discarded.
