If I explicitly tell IE (still using IE8 in-house) to use GCF with the gcf prefix Chrome is activated. Downside is any links internal to the target site loose the gcf prefix thereafter. Expected.
Added X-UA-Compatible in the HTTP in Apache of "IE=edge,chrome=1". GCF is never activated. Think this is a general problem with our packaged version of IE8. It seems to ignore all X-UA-Compatible directives.
Wondering if anybody has ran into the same issue? Or if there are log files I can look at? Or increase debugging?
