Hi. I have a public spreadsheet document which I retrieve the values feed for. Before retrieving again, I want to use the eTag along with the GET html header to only retrieve if it has changed.
But I do not see the etag value in my original receipt of the feed xml? Am I looking in the wrong place? Values feed: https://spreadsheets.google.com/feeds/cells/0ApxVGpvNN1kZdEhORnZnbi11ZTB5TXJsZFM5YTNkRmc/1/public/values Thanks.
