as others have suggested, you can use an SSL tunnel for
this application. You could also use SSH's port forwarding
facilities. However, note that this will not prevent an
attacker with access to the network from discovering that
you are using HTTP -- the pattern and timing of requests
sent and replies received is likely to be quite
characteristic of the protocol. This sort of traffic
analysis will not reveal which web pages you are viewing
(unless your client leaks that information in other ways,
for instance by doing DNS queries for them) but it will
reveal that you're using HTTP, or another similar
protocol.
