Hi Elliott,
That's actually not an error, but could be an indication of what's
happening. The Calendar data API does use redirects for the purpose of
handling sessions. Please see the following KB article for more info:
http://code.google.com/support/bin/answer.py?answer=55833&topic=10360
The only difference in the URL you were redirected to is the gsessionid URL
parameter. As you were able to delete the event from your calendar using
this URL via curl, it doesn't seem as if there is an issue with your
calendar account or the like-- something is happening incorrectly between
your code and the client lib/mono/something else.
Try doing something like the following, as is shown (in a slightly different
way) in the unit test cases:
service.RequestFactory.MethodOverride = true;
This enables using POST with the override header I wrote about earlier.
Also, look at the GDataLoggingRequestFactory -- this will provide some more
logging information if used in place of the normal factory object.
Cheers,
Ryan
