How do you set handler mapping to a directory in IIS 6.0?

[htinc]

I have IIS 7.0 on my development machine and IIS 6.0 on my server. On my development machine I was able to set a handler map on a directory within my site called /ViewHtml/ and I mapped it to asp.net. In my global.asax I check the request sent to asp.net for /ViewHtml/ and I serve the appropriate html file(html version of a Doc, Power Point, or Excel file) located outside this apps virtual directory. I am doing it this way because all files are permission protected, we didn't want to put these files in are database due to scalability, and I need to hide the path to these file on the server. This all works in IIS 7.0 exactly how I would like it to. Although I have not been able to get my IIS 6.0 server configured to map all requests to that directory to asp.net. Any ideas? Thanks Guys?
