I was able to solve the session state issue using another 
product.  I did this by first passing the form through the 
products integrated browser and then subsequently 
accessing the target page through the same browser.  

If you'd like more details concerning the resolution, 
contact me.  I just wanted to let you know that I am no 
longer looking for a fix, just in case you are still 
working on the issue.  Thanks for your effort.
