And this kills proxies as the systems behind a proxy will switch from a mirror already cached by the proxy to another one potentially every hour. Proxies want a static mirrorlist or a mirrorlist they can cache. (using a mirrorlist URL with parameters is probably sufficient to make it uncacheable, better static URLs with mod_rewrite or something similar behind to translate them in hidden requests) >> - yum should generate proxy-friendly metadata > > It's static files from yum, yes? What's not proxy-friendly about > that? The static files do not use a mimetype that allows embedding expiration period, so unless the mirror admins configure their http server to add correct expire info for those specific files in the HTTP response (no one will bother) proxies will fall back to a default retention policy. Usually that means "keep the files x hours/days, and only check later if they've been updated". Every yum behind the proxy will then use a cached metadata version that does not correspond to the actual mirror content and will trigger problems. (typically yum asks for a package which exists in the cached metadata but is no longuer on the mirror and has not been cached in the proxy when it did exist -> boom) If you are behind a non-mandatory proxy you can configure yum to ignore the proxy for metadata (lots of hassle when you have to change the default config of many systems. Also this option only exists because the current system does not work with proxies) If you're not you're out of luck. A proxy-friendly metadata would probably be an xhtml index file (with correct HTML expire metadata) pointing to xml.gz files that change name every time they're regenarated. Other people may have better suggestions. -- Nicolas Mailhot -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
