Thanks for the PR. Just bear in mind to fill out the template i.e. How Has This Been Tested?

Hi @alexellis, @viveksyngh

Sorry to hijack this PR, but I opened a similar, but more extensive issue (#205) in May. In it, I proposed opening a PR with my tried-and-tested solution, but since I got no response on the issue, I didn't at the time. I've now created it as #217.

Imho, my solution is less hackish, as it parses standard headers and doesn't require environment variable definition. It also is more extensive in functionality.

I'd be happy to propose similar changes to the flask templates (actually have those running privately too).
