Enable Cors on Any Host

[seikosantana]

How do i enable cors from any host? I tried
restServer.UseCorsPolicy("http://*");
and
restServer.UseCorsPolicy("*");

But neither worked. Invalid URI: The hostname could not be parsed.

Wouldn't this be the same as disabling CORs? If that is your objective, just don't include the CORs middleware.

Nope, i'm trying to enable cors for any origin..

[scottoffen]

sever.UseCorsPolicy();

This adds OnRequest middleware that does the following for all incoming requests:

context.Response.AddHeader("Access-Control-Allow-Origin", "*");
context.Response.AddHeader("Access-Control-Allow-Headers", "X-Requested-With");

There are additional extensions that take parameters that allow you to configure the CORS policy to your liking, but this approach does the wild card CORS, which is what I think you're asking about.
