Re: File Download from Web

Thanks for the input. Both methods are to have the file displayed in the browser window. But this is not what I meant. When a user clicks the link, I want a file download dialogue window to pop up, so the user can save this file to the local computer. This automatically happens when the file is a .tar.gz type file. But if the file is a .txt file, it's displayed in the browser window. So is there a way not to have the .txt file displayed but to pop up a file download dialogue window when the link is clicked? Thanks

Your program needs to send the file to the user itself. When you click a link you are linking to the program and not to the file, something like: `<a href="/yourprogram.cgi">Click here</a>` [download] The program must spit out the correct headers. One of these should probably be 'content-disposition' so I suggest you poke around based on that. Be wary of specifiying the file in the link unless you know EXACTLY what you are doing, otherwise this can happen: `<a href="file.cgi?file=../../../etc/passwd">here</a>` [download] Ok thats a contrived example to indicated what I mean but that should indicate the problems you face ;). If you are not careful someone could download any file on your system which is something you definitely wouldn't want :).	[reply] [d/l] [select]
