Change subject: Expose some headers to CORS requests
......................................................................
Expose some headers to CORS requests
For the launch of Media Viewer 0.2 we want to measure detailed
network performance or image loads. In production images are
always hosted on a different domain, which causes a CORS request
when we measure the performance with the Navigation Timing API.
Browsers block reading some headers we're interested in unless the
header added in this changeset is present.
This will allow us to measure the image load performance of
varnish hits vs varnish misses in production, which is a critical piece
of information for Media Viewer.
