问题描述： After upgrading to Mac OS X 10.6 or create a new account in you mac, you may be unable to access expected web site content (in your ~/Sites/ folder) via Web Sharing. Web Sharing appears to be enabled and working correctly, but trying to load your web site results in a “Forbidden 403” Web page.

	Options Indexes MultiViews
	AllowOverride None
	Order allow,deny
	Allow from all
</Directory>
  4. Replace the word “myname” with your user account’s shortname. (This is the same name as the user’s Home folder in the Users folder.)
  5. Save the TextEdit document on the desktop with the name “myname.conf” where “myname” is the shortname.
  6. At the prompt, click “Use .conf”.
  7. Quit TextEdit.
  8. In Finder, from the Go menu choose Go to Folder.
