    I need a link that forces the 'save as' dialog for a file which would usually load in the browser window. Anyone know how this is done?

    Cheers, though I should have specified I'd much prefer something in PHP.

    I think the PHP header function might do the trick.

    found this to,
    might make sense to you as you php -

    <?php
    header("Content-type: application/x-unknown");
    header("Content-Disposition: attachment;
    filename=proposedFileName.wav");
    readfile('test.wav');
    ?>


    "Content-type: application/x-unknown seems to be the imporatan but as it tells the browser that even though it recognises the extension, it doesnt know what to do with it

    As pointed out it's not possibly using HTML alone but it realatively easy to script a streamed download that will use header functions with 'Content-Type' and 'Content-Disposition'.

    If you are dealing with a particularly large file be careful how you implement it as there can be a large memory overhead (and a delay) in providing streamed downloads where the entire file is read in first and then streamed out.
