Hi,I have a Struts 2 application with Tomcat 7 that runs on a proxy network. In
one partcular case while browsing the applicationit was observed that simply
navigating one particular screen multiple times raised a NoSuchMethodException
exception once.This was observed in IE-10 browser running on Windows 8. It was
occuring on a single system only and could not be reproduced on other
systems..The request as obatined in Tomcat catalina logs is as
follows:192.168.103.105 - - [14/Jul/2016:15:41:54 +0000] "POST
/application/framework/SessionAction.action HTTP/1.1" 200

/application/framework/SessionAction.action HTTP/1.1" 200 58209Also when
used Internet Explorer to debug the request we get the following details for
the problem scenario:Request HeadersKey Valu
