I think you are mixing up client and server processing.
When you have a URL like
http://www.mysite.com/myfile.pdf#page=21
what happens is this
1. The CLIENT sees the URL.
2. The client parses the URL and contacts www.mysite.com using http.
3. The client sends a request for /myfile.pdf only
4. The SERVER returns the PDF contents
5. The CLIENT processes the returned contents and goes to page 21 once the file is opened.
Nothing in the above discussion is broken when the server process is an ASP, whatever methods it might use.
HOWEVER, using an ASP will break "fast web view" processing and will lead to much slower display of large files. But in this model, the server can't know what page is required or speed things up.
A much more complex ASP could support fast web view by honouring HTTP/1.1 protocols for byte retrieval, but that is too advanced for most people. Still, you must generate the whole PDF, and serve only the portions requested by the CLIENT.
