Sinatra access-control-allow-origin for sinatra public folder

Question

How do I set up Sinatra so that static files in the public folder are returned with the response Access-Control-Allow-Origin = \"*\" ?

Answer 1

Have a look at this question here: Sinatra OPTIONS HTTP Verb. It's implemented in sinatra now so you don't have to hack around it.

If that doesn't help take a look at this blog post: Cross Origin Resource Sharing with Sinatra, and its repo at github: sinatra-corss_origin

Although the simplest way to do it should work just by adding this:

response['Access-Control-Allow-Origin'] = 'http://whatever.org'

before the return value in your route.
