Realy cool, I was thinking the same but for 2 years or something like this. Because in Apache you can manipulate Error-Messages, it is possibel. The problem is only the TimeOut of 'apt-get' if the requested Server is not fast enough. I hve done this already in a php-Script, but unfortunatly my apt-404-proxy-cgi does download the File and then forward it to apt-get. I was not able to stream it while downloading. > For Release, Package, Sources, and Contents files, we need > a RewriteRule.

Hmmm for those files I have a cronjob, so there are allways the newest versions availlable. > How do you send the newly retrieved file instead of the static file > present on the filesystem?

If an error occurs, the Refer URL is paste to the Error-404-CGI. and while the CGI download the file from a Debian-Mirror, it can stream the Error-404 as "application/x-debian-package" while rewriting the HTTP-Header from 404 to 200. > I think this would be an extremely simple implementation, using the > proven apache for most of the work (and not the buggy twisted module > that apt-proxy uses).
