916 Area Code. On February 09, 2017, the California Public Utilities Commission (CPUC) approved an overlay that will add the new area code 279 to the 916 area code region.
In computer networks, a proxy server is a server (a computer system or an application) that acts as an intermediary for requests from clients seeking resources from other servers.
To the user, the proxy server is invisible; all Internet requests and returned responses appear to be directly with the addressed Internet server. (The proxy is not actually invisible; its IP address has to be specified as a configuration option to the browser or other protocol program.) See an introductory video explaining proxy servers (definition continues below): Users can access web proxies online or configure web browsers to constantly use a proxy server.
