It did not work. Then I tried the example above it, setting the href to point to where caldav.php really is. No joy. This particular server was originally just a mail server, so DocumentRoot points to SquirrelMail. When I added DAViCal, I did Alias /cal/ /usr/share/davical/htdocs/ <Directory /usr/share/davical/htdocs/> AllowOverride None Order allow,deny Allow from all </Directory> And users go to https://mail.example.com/cal/caldav.php/username/calendar Which works just fine. Adding Alias /infcloud/ /usr/share/davical/infcloud/ <Directory /usr/share/davical/infcloud/> AllowOverride None Order allow,deny Allow from all </Directory> Allows https://mail.example.com/infcloud/ to get to the login screen, but logins result in script '/usr/share/squirrelmail/caldav.php' not found or unable to stat, referer: https://mail.example.com/infcloud/ in the error.log and Info: [globalNetworkCheckSettings: 'https://mail.example.com/caldav.php/']: crossDomain set to: 'false' Failed to load resource: the server responded with a status of 404 (Not Found) In the JavaScript console (Chrome). As regards the readme.txt Item 2 doesn't really *clearly* explain what is cross-domain and what is not. It gives examples, but does not clearly note which is which. At least not to *me*. In config.js The comment lines really badly need to be wrapped. I've currently got an xterm window blown out to 237 columns wide, and it's still not wide enough. Makes reading the thing very difficult. For me, anyway. Near one example it suggests that, for cross-domain setups (which I'm still not certain I have or not): misc/config_davical.txt. That turns out to be some Apache rewrite rules... with no explanation as to what to do with them. Regards, Jim -- Note: My mail server employs *very* aggressive anti-spam filtering.
