问题 When I look at this published Google Docs document, I see the latest version with Firefox and Chrome , but an older version with IE8 .

No matter what headers I try to change in PHP/Curl, I can't get it to show me the newest version.

问题 I am having a problem with the umbraco cms. We are using umbraco 4.6.2 with .net usercontrols.

However, the Set method doesn't return the item that was
