Abstract: In various embodiments, a client application requests information relating to content servers from which particular content can be accessed, or a manifest server that maintains such information and is distinct from the Domain Name System (DNS) automatically determines that the client application is likely to request the content server information. The manifest server then transmits, to the client application, information specifying (1) hostnames associated with the content servers from which the particular content can be accessed, and (2) Internet Protocol (IP) addresses corresponding to the hostnames. Thereafter, the client application can use the IP addresses to connect to the content servers and validate certificates provided by the content servers, in order to establish secure communication channels with the content servers.
