Re: IE11 Compatibility Mode not supported. How to handle it?

See (beware that those properties use eval() so are possibly unsafe and/or won't work under a strict CSP; you could customize the CrossSiteIframeLinker with a different processMetas.js that doesn't use eval())

Alternatively, use <set-property-fallback> to avoid the error, then use UserAgent in your entry point to check the browser and bail out.

As it was an uncaught exception, I was able to catch it in a global handler.  Not a great solution, but it works.

<script type="text/javascript">
.onerror = function myErrorHandler(errorMsg, url, lineNumber) {
if (navigator.appVersion.indexOf("MSIE 7.") != -1) {
("Sorry, IE7 is not supported.");
} else {
("An unexpected error occurred: " + errorMsg);
return false;

Any better ideas will be much appreciated.  :-)
