Flash upload keeps going after page refresh

Question

I have a rather strange problem, well strange to me.

I have a file upload tool that I created in flash (as2). The file uploads images and then writes the image details to a database. However, I seem to have a problem then when I refresh the page, the upload script keeps working.

And this seems to cause some issues with writing to the database when image don't actually appear to be on the server. I have fixed the issue by doing some checking to see if the file actually exists before writing to the server, but I would like to know why this happens.

Anyone had this issue before?

That could be because your swf is being cached by the browser with the process still running in the background. I would suggest you force the browser not to cache by adding this to the head tag:

<meta http-equiv="pragma" content="no-cache" />
