Upload memory data instead of file

Hi,

I have a third-part servlet which will deal with a jsp's upload control. In my jsp page I got a string data that the servlet needs. Can I simulate a file upload control in my jsp page to submit the string data to the servlet insteat of creating a real local file, which i have to browse it and delete it later?

Thanks in advance.

Are you saying you want the browser to trick the server into thinking it's sending a file when it's just sending a string from memory?
I doubt you'll find a way to do that.

The Javascript XMLHttpRequest object does allow you to set request headers.
You might want to play around with that to see if you can spoof a multipart form request. Could be fun to try.

The folks in the HTML/Javascript forum might be able to give you more information on it.
