A network-based naming service using HTTP, with in-memory caching.
Fetches from one or more remote (in-i2p) CGI services using HTTP GET.
The remote HTTP service takes a CGI parameter and must return (only) the
516-byte Base64 destination, or hostname=dest.
A trailing \n or \r\n is acceptable.
Should be used from MetaNamingService, after HostsTxtNamingService.
Cannot be used as the only NamingService! Be sure any naming service hosts
are in hosts.txt.
Supports caching, b32, and b64.
Sample config to put in configadvanced.jsp (restart required):
