[CalendarServer-users] iCal/DCS handling URLs with "@"

[Peter Mogensen]

Hi,

I have users on DCS were the username is an email address (containing @) 
on a modified DCS where the calendar-home-set URL is:
/calendars/user at domain/

When I try to connect with iCal it askes for calendar-home-set for
/principals/users/user at domain/ and correctly gets a DAV:href element 
with /calendars/user%40domain/

Of course @ doesn't need to be encoded, but from what I can read in the 
WebDAV RFC, this is legal syntax for a DAV:href element.

BUT:
After that iCal askes for PROPFIND on  /calendars/user%2540domain/

I know I'm on my own when modifying DCS, but my point is that there must 
be a bug in iCal when it tries to re-encode the already encoded URL 
delivered by DCS. The bug should hit any iCal user using a CalDAV-server 
which returns URLs containg @, which makes interoperability difficult.

regards,
Peter
