Preferential selection of ip protocol version with domain name matching on proxy servers

A satellite gateway, comprising;

• a web acceleration server for receiving a request from a requesting device;
• a cache containing a domain bypass list including a list of learned, preferred Internet Protocol (IP) version to domain name mappings, wherein the web acceleration server determines whether a domain matches an entry stored within a domain bypass list in relation to the request;
• at least one processor;
• and
• at least one memory unit storing program instructions adapted to cause the at least one processor to:
• upon a determination that the domain does not match at least one entry stored within the domain bypass list, look up the domain in the cache;
• and
• upon a determination that the domain does match at least one entry stored within the domain bypass list, determine whether to allow or block one or more types of traffic based upon a preferentially selected IP version, the preferentially selected IP version comprising at least one of an IPv4 address and an IPv6 address.
