This helped us identify the response that did not have the header. We noticed that we have a static html called signon.html as our first entry into the application. Since this is a static html, our servlet changes to add response header does not hit when users invoke this signon.html. I think Chrome puts this origin into Origin-keyed cluster at this point and hence when users login and encounter document.domain, they get the error blocked frame error.
meta tags with http-equiv does not recognize this custom response header Origin-Agent-Cluster. Is there a way to add response headers in a static html page response?
