Live Outlook Calendar on Web

I saved my calendar as a web page, and it shows all of my appointments. I
like this feature, but would like the version on the web to be updated
without having to "file" "save as" everytime I have a calendar change.

Can autoupdates be sent to the web server using ASP, PHP, etc? If anyone has
any code or methods, please post.

I also tried the .vcs method, but users were unhappy with having to
"download" a file everytime...Go figure.

Thanks
