Re: [WSG] force download a media file
Hi all, I am very glad and thankful to you all for your time to respond to my mail. Thank you all for the advice and tips given. Actually when i used force download what i meant was the save as window to come instead of the media file being played by the browser (thus giving the freedom of choice to the user). In the mean time, i could find out that my server supports CGI and pearl..but m not familiar with these technologies. I did be glad if someone can help me in this. thanks in advance.

I've been following this thread, with its discussion of headers, MIME types and content-disposition, and I have to say that your post suggests a fundamental dilemma, even before you get to all the server-side shenanigans: you can't force your visitors to do anything - and especially not if you want to 'give them choice' as well! The web is unique, in that it's a user-configurable medium. In the same way that we shouldn't try to serve the same pixel-perfect layouts to every visitor, you shouldn't expect to be able to 'force' your visitors to download a file. If their browser is configured with a helper app that handles your file inline, let it happen! Savvy surfers expect a measure of control - or at least the illusion of control - over their experience. That's why you hear, over and over, not to use pop-ups, new windows, or other practices that take that control out of their hands. They don't like it - and they'll go somewhere else. 'Podcasts' all over the web (and I quote the word because it's becoming a generic term for a downloadable audio file) are supplemented with a single, simple instruction: 'Right-click (or Control-click) and choose Save As...' Now *that's* giving your visitors choice.

Re: [WSG] force download a media file
The choice on how to handle any MIME type is in the hands of the downloading application and cannot be controlled by the source site. If it was not for this, it would be too easy for a site to infect any target operating system with malicious intent.

was just going to say that you could set a header with PHP, but then noticed that you don't have it.

Re: [WSG] force download a media file
In regard to content-disposition The following RFC states (very late in the text in the section on Security) In general, the receiving MUA should not name or place the file such that it will get interpreted or executed without the user explicitly initiating the action. http://www.ietf.org/rfc/rfc2183.txt So - while it may seem like content-disposition is an answer, a well behaved MIME-type interpreter should still ask the user what they want to do with the file. So, this still does not (or at least should not) allow an MP3 (or any other file) to be run or executed without the users intervention. At minimum, the behaviour for content-disposition is not guaranteed. In fact, some browsers continue to be naughty in that they actually DOWNLOAD the file first (to some temporary location), then fire up an appropriate application to handle the MIME type against the downloaded file rather than running the handling application as a plug-in (freestanding or embedded) and passing it the address/URL of the resource to process.

Re: [WSG] force download a media file
And I forgot to add... By the time you could execute Javascript (and that would not be possible once the MIME type has been specified) the browser would have already decided what to do with the content (NOTE: I cannot see how you could execute any JS once you were outside of the HTML MIME type).
