can any one help me.  
i created one application to track the people opening the mails which is  
send by me from my application. but one problem which became an  
obstacle in my path is when any use say tony opens that mail once  
his count in db is one,but his count will not increment when he go  
back to his inbox and click the mail again.for that he had to  
refresh the inbox, means had to press F5 to clear the  
cache.actually inorder to track the open users i am passing an image to  
the controller from view page

is there any methode to avoid this?

or any method to clear the cache.please help me

Thanks;  
Tony
