Low speed, unreliability and cost of communication are the major
problems of mobile web access.  Circumstances where communication is
totally unavailable should also be considered.

We have devised a proxy-based system to optimize the communication via
weak connectivity and to support caching and hoarding contents for
future access.

In particular, we have added priority mechanism to MUX protocol to
control the order of transfer of multiplexed HTTP streams over one
TCP connection.

Caching and hoarding are also being implemented in a
client-transparent way.

We would like to standardize and coordinate these methods with other
protocols in our activity at W3C.
