The XMLHttpRequest spec says "The setRequestHeader() method appends a value if the HTTP header given as argument is already part of the list of request headers." This is fine but what is a problem is whether or not a new XHMHttpRequest object has any default headers. I was trying to use the Accept header a few days ago and I wanted to have only Accept: application/json but Opera has a default header Accept: text/html, text/xhtml, etc so my application/json was appended to the front of that list which makes my Accept header useless as part of the client-server communication. The server thinks that the client knows what to do with text/html. My JavaScript certainly does NOT know what to do with text/html. My JavaScript only knows how to handle application/json. I think all XMLHttpRequest headers should be specified as blank when the object is created. Then the JavaScript can add any headers it needs to add. If, when the call to send() occurs, some essential header(s) is missing the XHMLHttpRequest object should add these automatically but only according to specified behavior. Peter
