Help with File download

I am using File upload and download in my application.
When i try to download the file browser IE6 gives two options. open and save. when i click open it gives an error with the mmessage.

cannot find file filename in some temp location. do you want to open a ne w file. Is this because i have to set some thing in my action class? please help me on this.

I am sorry to push this post forward. But this one is urgent. If anyone has got some idea please help me with this.

I have solved this by not setting this response header "cache-control". But now if my dowload file type is .txt i am not getting a prompt and the browser opens the file automatically on click. Can i set some response header which will force the browser to prompt before the file is being opened?

Are you setting content type in header.

How are you downloading the file, is it direct link to the file or you are writing it to response (through servlet or JSP)?

I just worked with file upload/download without any problems (for different file types, XML, XLS, PDF, CSV and off course HTML)
