FileUpload control, V Studio 2005

[gem1204]

I’m using a file upload control on a web form so a user can upload a picture. After uploading the picture the user has the option of going to another form with a link I have provided. I want the user to be able to use their browser’s back button to return to my upload form, but after uploading a picture and then following the link and then using the browser back button he gets the message When using the br

The page you requested was created using information you submitted in a form. This page is no longer available. As a security precaution, Internet Explorer does not automatically resubmit your information for you

I know the problem is that the file upload control has uploaded a file and the file is still in memory or cach or in the HttpPostedFile collection. How do I clear this so that when the user clicks the browser back button he can return to the upload form if he wants to upload another picture?? I have tried Response.clear and Response.Expires = 0 but neither of those worked.

How do I clear the information after the file is uploaded?

Thanks
