My solution, which is in the current CVS of Xastir, is implemented simply
by giving each downloaded map gif an individual name, saving all the files
to a directory under the users ~/.xastir/ dir and keeping a persistent
database of the mappings from the requested URL to the saved filename.

What needs to, and is being added to this cacheing implementation is some
management of the data stored in the cache.

Certainly, a Squid or other proxy isn't mutually exclusive to a built-
in Xastir map cache.
