1) not *conceptually* different and

2) the file's not being parsed (unless ASP has no direct file
      system access methods - I don't know, I've only used Perl
      and Java for this).

I never suggested that there wasn't a possible performance impact.
Still, your diagram's wrong.

client ->
        web server request handler ->
               web server* request servicer ->
                          system file I/O handler ->
                                 web server* request servicer ->

* the web server "request servicer" can be a builtin module, or a
CGI program, JSP/PHP/ASP interpreter, whatever.

Whether performance in any given specific situation is an issue,
only you can decide. Me, I'd test before making assumptions :-)

Hope this clarifies,
