i think i see what you're doing...

after someone selects a product (they submit a form), it goes to a 
cart page to show the user what is in the cart... so there are two 
pages the user sees...

product page:
- kill 'foo' session variable when page is requested...
- allow user to submit to cart...

cart page:
- check for 'foo' (if it's not there, this is from the product page, if it is 
there, it's a reload so do nothing but display the page)...
- add item to cart...
- set 'foo'...
- display cart (with options to add more items, returning the user to 
the product page)...

any better?

there may be other factors at play on your end... i'm just offering a 
simplified approach...
