Maybe this is along the lines of what you are looking for.

In the example I gave, I mean the whole thing is loaded once, then every
session can use it. Basically it is like a cache, only it is available cross
sessions.
Clearly one can use DB to store data to do that, however, (1)there are
things that are not suitable to store in a DB; (2)DB is over-kille

This is the sort of thing we call a scalability killer. Loading
everything into memory on one machine and then adding locks presumably
for writing to this memory means you are limiting any sort of horizontal
scalability and you are slowing down the one machine you do have with
lock contention.

Aiguo,
To achieve good performance, I want to load the
whole dictionary into memory when the "application" starts (e.g.,
when
the web server starts...
I'm not sure how ASP works, but in PHP you can't load something into
memory when the web server starts and keep it there. PHP 'compiles'
In ASP.Net there is the concept of "application" which is a virtual
directory on a Web server. An application can have application-wide
shared data/objects, which can be accessed by any script of that
application (i.e., scripts under the virtual directory). I have gone
through several PHP books, ha
