Crystal reports solution in ASP.Net site fix for session state post backs

I am looking for a solution that needs to work in session state out of process that will allow the page to only post back when a report is selected to run. The screen will have multiple, reports for selection and when the user selects one and clicks a run button then the report is produced on the same screen, When the page posts back to reload for the Crystal reports viewer clicked for go to next page or enlarge report then this will reload the same stored session report. Remember this can not be stored in session more than likely it will need to be done using ASP.Net state service unless a better solutions can be found. This is more like a help than a project I need doing There will be a master page in the solution with sub page and a user control on this page and I would prefer to use Ajax as well I will need a .Net project using 2010 and Crystal version 13 with the working reports. These can be dummy with any SQL back end it's the way the framework will do it not the reports I will supply screen shots for the way it looks it will help understanding when I accept the winning bid
