a web page can be treated as a directed graph, so a web site can be
understood as a collection of directed graphs
.
I know there are CMS that keep whole web sites in databases, but I was
wondering how this is done. For example, given a number of paragraphs with
the same prior path on a page how do they distinguish the 3rd from the 7th
if they use just the path to the particular node.
.
Checking the Last-Modified HTTP header is way to coarse. Isn't it?
.
What about if you want to only specify exactly what has been modified and
where (in the page graphs), so that the page can be minimally updated.
.
What is the smart ways to do something like that?
.
I am a total newbie on the subject, but I have always wondered why things
are done that way (such things as "Last-Modified"). Any thoughtful
discussion on the subject?
.
thanks
