Michel:

Selecting refresh button from browser will get you back to server, but just hitting a return at end of URL or selecting URL only brings up a cached page.

Adding a Response.ContentTypeHeader('Force Reload') before Response.Write() solves problem programatically. Using StandardPage() also works.

It must be something with way I'm formatting HTTP output. Possibly using response.write() in this context doesn't build a completely valid HTTP ouptut. Need to look into it further.
