To be able to resolve both ISSSUE-91 and ISSUE-92 I introduced a "send() flag" in the CVS edition of the XMLHttpRequest draft. When send() is invoked the "send() flag" is set and when that flag is set invoking send() or setRequestHeader() raises an INVALID_STATE_ERR exception which seems to be consistent with some implementations (notably Internet Explorer) and at some point (hopefully) all implementations.
This "new" "send() flag" is only relevant when readyState is 1 (Open). -- Anne van Kesteren <http://annevankesteren.nl/> <http://www.opera.com/>
