link to download a file

kalyansarkar108 · November 28th, 2005, 07:46 AM

I have a jsp page that contains a link to a file. On clicking the link the file opens in the browser itself. I want to give an option "Would you like to open the file or save it to your computer?". How can I do this? Can anyone help?

Here is my code...

<td class="tbdataleft" align="left"><a href='file:C:/file.doc' class="red">file.doc</a></td>

The open/save dialogue appears automatically if the file is of a type the browser does not understand.

To force an open/save dialogue, you must alter the HTTP response headers. I don't know how it's done in JSP, but in PHP it looks like this:

Code:

// Put in whatever MIME type or leave this one
header('Content-type: application/octet-stream');
header('Content-Disposition: attachment; filename=suggested_file_name.whatever');

// Grab and output the contents of the file.
echo file_get_contents('/server/path/to/file.whatever');

HTH!

Regards,
Rich
