The reasons of this little project

Recently I had a little problem on a Websphere application server. A JSP page running on this application server had a problem (a no ending loop). This was a bit hard to identify because noting permit to isolate on this server the pages running.
To solve this lake of informations I realized a little Servletfilter which permit to monitor this.
I propose you this little tool for exemple as a ServletFilter. I wish it would be useful to you.
