Support Redirects

[eMerzh]

Hi thanks a lot for your project,
it's really interesting!

i'm currently re-writing a website with flask-frozen and hopped that i can deploy with your tool.
but one thing i miss is a way to do redirections.
it seems that you can add a x-amz-website-redirect-location header or smth.

if you could add this, it would be really cool :)

keep the good work! 👍
