I am looking for a way to run some asp code within pages with an html extension. I don't want to create new pages and do a 301 forward and I'm trying to avoid an iframe.

My site is hosted on IIS 5 and I verified that asp does work.

I know that you can add an application extension to force parsing for any extension, but I don't have shell access and it looks like that applies to the whole server anyway, not just one site. My request to the host admin was ignored.

I read that you can run it in a <script> tag, but it didn't work (not surprised).

Any ideas?

If the hosting company won't (I usually suspect can't because they don't know how) add the app mapping there isn't a lot that can be done.
Adding application mappings can be done on a site by site basis provided you have access via the MMC.

And of course there are always frames...

There are, but...

yeah, app mapping seems to be the only answer
some control panels like inspanel give web interface for it
