Nathan,

>I'd bet that COM component has some internal storage for cached pages,
similar to Net.Data.

Technically speaking, it's processed by a .dll, but I don't believe the .dll
is a COM object, as Sigmond said, sometimes a .dll is just a .dll. As far as
caching, it may have caching, but I know it will detect a change in the .asp
file and use the new one as soon as I put it up there. Now, ASP.NET actually
"compiles" the asp file the first time it's used, so you could argue that
there is caching there for sure.

>Other ASP programmers who I know like to create their own COM components
for business logic.

Most other ASP programmers are using SQLServer or Oracle or the like on the
back end. ASP has no real facility for business logic, nor does the database
manager. SQLServer and Oracle both have quasi-programming languages in their
stored procedures but nothing I'd implement real business logic in so the
only choice left is COM. Actually COM isn't bad, however, in the case of an
AS/400 back end we have great languages in which to implement business
logic: RPG, COBOL, C, C++, etc. When you define a SP on the AS/400 you can
say it's implemented in xxx program. When that SP is called from the ASP it
is really just a call to the xxx program passing it the parameters. You can
do anything you want at that point.

> The RPG program writes the HTML page.

Ah, but then you haven't completely separated your business logic from your
presentation have you? Sure you could change the layout of the page, but
what about using the same logic to process XML, or exposing that logic via a
Web Service using SOAP? You'd have to rewrite the AS/400 program again, no?
