that could bring up a whole host of copyright issues and hoards of

you still have to deal with people clicking 'reload' or otherwise
forcing a re-fetch; and is saving time on one single transfer (the
pre-fetch versus the first client to request the file) really worth

Actually reminds me of another problem: you can fetch
documents from their servers using a variety of names: (preferred?),, www{n}, (old browsers),, etc... all affecting
the efficiency of a cache. (They're not the only guilty party, though.)

Some sort of host-aliasing directive (One could take it a step
further and implement URL aliasing, but then you might as well use
the redirector, as others are doing) could possibly be simple to
put inside the core Squid code?
