Comment #13 on issue 8935 by [email protected]: Gmail calendar widget  
doesn't load
http://code.google.com/p/chromium/issues/detail?id=8935

See the WebKit bug for more information:
https://bugs.webkit.org/show_bug.cgi?id=24957

The Widget requires XHR to be able to set Authorization headers, which are  
currently
disallowed by the HTML5 XHR spec.

Relevant section of the spec:   
http://www.w3.org/TR/XMLHttpRequest2/#request-metadata
scroll down to the section "When setRequestHeader() is invoked, the user  
agent must
follow the following steps (unless otherwise indicated)..."

The spec suggests that having a different header is a workaround with these
limitation, "The above headers are not allowed to be set as they are better
controlled by the user agent as it knows best what value they should have.  
Header
names starting with Sec- are not allowed to be set to allow new headers to  
be minted
in the future that are guaranteed not to come from XMLHttpRequest. (Older  
clients
would however still be vulnerable as they allow such headers to be set.)"
