APM Sharepoint authentication v2

I have two issues after a quick test.

I had to add this to make it work with office web apps (sharepoint 2013): if {[HTTP::header "User-Agent"] equals "MSWAC"} { ACCESS::disable ECA::disable return }

I have the same issue with the irule I wrote for my setup. And another similar error which I've always seen but never dealt with as I'm still testing my setup. Java script error when opening office docs with office client right before the logonpage. the error comes from apm script having issues with the mini ie browser. https://webapp1.com/public/include/js/web_host.js error line 35 => return (window.external && typeof window.external === 'object');

DefaultExternalWebHostImpl.prototype.isAvailable = function() { return (window.external && typeof window.external === 'object'); }
