I have noticed after making a public calendar for sharing in Google Calendar that none of the URL shorteners I know work with importing inside of someone else's Google Account (Apps account or not) due to the robots.txt blocking crawling (of course, just surprised GCal requires a crawlable URL).
I am wondering if anyone here knows of a way to shorten a public GCal link and still make it accessible?
301 Moved Permanently... so it's likely the Calendar import doesn't follow redirects. Since it's all internal to Google, I would not be surprised if it tried to extract some identifier string from the URL rather than actually following it. – Bob Apr 20 '12 at 9:39
