I don't know about BV, but I did some template development in Vignette.
in Vignette, a page is generated on the fly, but only when the first user
sends a page request to the server.
After that, StoryServer caches a version of the complete HTML page, which
is downloaded when subsequent users request it. This serves to greatly
reduce the load on the server since it has to generate a page on the fly
only once, until the data is updated and the stored HTML page is "flushed".
IN this way, Vignette is optimized for a site that has enormous amounts of
traffic.
The cached pages can be flushed from the server as desired, and are in fact
automatically flushed when a template is altered. when content is altered,
flushing is not automatic. they can be flushed one at a time, or flushes of
entire directories can be scheduled. at large sites, this is typically done
at specific times of the day.
once a page is flushed from the server, it is generated on the fly next
time someone requests it.
the default URL (called a "cURL" for "custom URL") follows the format
0,XXXX,YYYY,ZZ.html,
for example in this ZDNET story:
http://www.zdnet.com/zdnn/stories/news/0,4586,2644020,00.html
The initial "0" in this cURL means that the page is automatically cached
after the first user requests it. if the first digit is "1", the page is
never cached (you would use this for something like a poll where data is
constantly updated, so you want users to see the latest info).
"4586" represents the ID of the template that builds the page.
"2644020" represents the article ID, since the main building block in
Vignette is "articles".
finally "00" represents customization capability for particular browsers.
this is not often used, as far as I have seen, and in fact "00" denotes no
browser specification.
