OK, now I have a question ... how does a servlet engine know the difference
between the mapping for servlet Z and servlet A? In other words, is the
difference between a file mapping and a directory mapping because of the
existence of the period in the Z mapping, or what?
I'm mostly concerned about how you tell the difference between an "individual
URL" match (which might be followed by some extra path information!) and a
"directory path" match. For example, what would you do with
"/file.html/extra/path/info"?
The rules that make the most sense to me are:
* "Longest prefix" match (except for "/"); else
* Extension match (which cannot include extra path info); else
* "/" match (i.e. the default servlet) if nothing else matches
without any special cases for exact pathname matching.
