Hi, What's the recommended approach to the filename used in downloads? I would like to allow users to specify the filename (or, say, use an existing user-provided name or title) which means I'd likely need to encode in utf-8.
But, I'm not sure what conclusion to draw from looking at http://greenbytes.de/tech/tc2231/ RFC2183 says the values should be 78 characters and limited to ASCII. 2184 and then 2231 discusses encoding but it seems not well supported if I'm reading those test correctly. See: http://www.ietf.org/rfc/rfc2231.txt Now, say I have to dynamically generate the download and it might take longer than a normal web request. In the past I've opened another window and used a meta refresh to poll the server until the download is ready. Seems a bit old-school. Can anyone point me to an example of a better approach? I've seem suggestions of using iframes or polling with AJAX. I've also see suggestions that it's important to not set no-cache headers for IE when sending the download. I'm not quite clear if I want to send Connection: close when polling. The idea is I don't want to hold up a web server process when the client is polling for the download, but the load balancer should allow for keep-alive connection on the client side but not tie up a single web server process. -- Bill Moseley [email protected]
