Hello, I am using Google calendar to display a series of user-
submitted event. The feeds are generated with php. I can add the feeds
just fine to Google Calendar -- however, any changes made in the CMS
are not reflected in Google Calendar, although they are in the feed
files. I had a similar issue some months ago:
Which I solved by modifying the headers -- now I haven't touched a
line of code and the feeds do not update again. Am I doing something
wrong? Have specs changed?

Tren -- you have to change the URL of your script and then re-
subscribe. That's the only way for me, but it's a pity that we get no
answers on what is clearly a bug!

Good luck finding the specs! I'm having to infer these things myself.

OK so a few things I think could be causing weirdness:
1. There's lots of blank lines in those files — I can't put my finger
on the exact point in the rfc where it says no blank lines, but I
can't put my finger on the place where it allows 'em. :S
2. You're not folding your lines as per section 4.1 of
http://www.ietf.org/rfc/rfc2445.txt . This has definitely caused me
trouble before.
3. There's a leading space in your UIDs; try removing the leading
space? Nothing in the spec AFAICS says no leading space, but
everything example element in the spec doesn't have a leading space.
I'm not associated with Google, so all of these things could be wrong
and I can only hope that someone from google will actually chime in.
I am having this issue with Apple's Mobile me service. I can add the
calendar using the "Add HTML" in Google Calendar, and it does an
initial load, but then when I delete events from the calendar, they
deletions show up right away in ical and on the ical.me.com/user/cal
site, however, google calendar just seems to have the cached .ics file
and isn't refreshing.
Why doesn't google calendar just refresh that calendar when you
refresh your browser or when you click the calender on and off?

I'm facing the same problem with my external calender not being
refreshed in Google Calendar after more than 24hrs. I spent ages
fiddling around trying to get it working only to eventually find this
thread which explains the problem. Very frustrating!
That would have saved me a lot of time. I'm sure I'm not the only
person who's taken a while to find this Google Group before
discovering this is known behaviour. I like the Calendar and want to
use it but sadly this issue is a stopper for me.
I'd have thought that respecting the cache headers would be the way to
go. This would mean that I could control when and how often Google
grabs a fresh copy of my ics file from my server. A manual refresh
method would also work for me. However there's already a "Refresh"
control at the top of the Calendar that clearly doesn't refresh
external calendar feeds. This is doubly confusing in my opinion!
So has there been any progress with this issue?
How long is it taking for Google to re-grab peoples' external ics
files?

Thanks a lot!
I got rid of blank lines and removed the leading space in UIDs and
still no joy. There is no way I can fold the lines as per RFC through
php, not that I'm aware of at least. But what really bugs me is that
my files *are* read by Google Calendar the first time, so I guess the
issue is somewhere else, not in the way my files are written. If only
someone from Google would notice this thread...
