Currently yum uses the http_proxy variable to determine which web proxy to use. In my environment, we have the following scenario * Fedora from local mirror * Custom packages from local server That works fine. We don't require a proxy for local access (and in fact don't permit the proxy to access local sites). Now, some users want to also add add-ons (fedora.us, livna, etc.) from servers across Internet. The problem is that we require a web proxy to access off-site web servers. AFAICT, yum has no way to deal with this arrangement where a web proxy is needed for some sites, but not for others. Would it be useful for anyone else to allow the http_proxy configuration in yum.conf on a site-by-site basis? later, chris
