State management

I have a web application which is hosted in a very large application portal. I enter the home JSP of the application when I click on the left hand panel where the link to my application lives. Based on a parameter that I set in session I display res[ective JSPs. Problem is when in a JSP if I click the left hand penel's main application entry point I end up showing the JSP I am in rather than the home JSP of my application. It is because my parameter is set to that page. How do I set the parameter to tha home JSP's page from anywhere? I have links to home JSP from my other JSPs also - HREFs that should take me back to home JSP. They are also not working because my parameter is already set to the respective current JSPs.

Thanks in advance for any inputs. I am getting a lot of help here for any question that I have and appreciate it heartfully.
