Parsing ASP or ASPX on clients?

Is there a way to locally parse ASP or ASPX pages on a machine running Win98
XP or Workstation?

An alternative I am considering is using calls to a DLL that basically
resolves what I otherwise would do in the .ASP scripts. (<A
HREF="c:\<appdir>\myDLL?<variables>">get Page</A>)

I need something like this for a desktop-application using HTML to present
the User Interface.

I know the solution is not really hard, but it has been 5 years since I have
sniffed on something like this, built by someone else, and do not have any
code or recollection left of it.

Thanks.
