   Hmmm - I think it would be a bad idea to hardcode something like this
into the standard.  URLs are supposed to be opaque to the client.

>A problem I see with this - is there a max line length for a GET command?

   Depends... there is if you farm out to a shell command (like
/cgi-bin/xxx).  I am not sure if any of the servers have a hardcoded limit
(I seriously doubt it, but you never know).

>Failing which we may be into using POST....

   This would be totally against the 'spirit' of post I believe.
