How can I navigate to and away from a Silverlight page in an ASPX website without having to initialize Silverlight each time?

I have an ASP.NET application that we will eventually be converting to a Silverlight application.
Currently, we are only porting over a few pages to Silverlight for the next release.

One of the pages, we'll call it ItemPage.xaml, will take an ItemId as a query parameter, and load some charts and tables with data.
Each time the ASP.NET application makes a call to the ASPX page that hosts this SL page, SL initializes and takes a while.  

I was wondering how I could set it up so that the page initializes SL only on the first call, and then any other page in the ASP.NET application
can make a call to that page (while passing query paremeters) without the additional overhead of having to initialize SL each time?

Any help you could offer would be appreciated.
