^-^-In %/Xitami/xitami.cfg -- the Xitami configuration file,
^-^-in the [Mime] section, add:
^-^-^-^-htc=text/plain
^-^-^-to allow the %Calender.htc hypertext component to be sent.
^-^-Caution: Hypertext components only work with MSIE!
^-^-Also, change:
^-^-^-^-js=application/x-javascript
^-^-^-to:
^-^-^-^-js=text/javascript
^-^-^-so as to correctly set the MIME for JavaScript files.
