A while back I suggested that we modify libwww to support variable
substitution in URLs, e.g., if "$xyz" is embedded in a URL, then
the browser should look in its internal symbol table and substitute
the value of variable "xyz" before dereferencing the URL.

Such a mechanism would make it easy to support dynamic links, e.g.,
<A HREF="$home">Home</A> uses a builtin variable "home".

We took a first cut at modifying libwww for this, and we're now using
it in our Windows NT browser (not for home and previous links, but for
variables set dynamically by embedded widgets -- for this we also use
simple conditionals in URLs).
