Hi friends of Espruino,

I hope that all ours are OK.
Now I'm trying to connect to a Http server made in Espruino like http://forum.espruino.com/conversations/334253/#comment14748665 from JS Client, but happen a error of permission about Access-Control-Allow-Origin because my JS Client is in another server and my Espruino web server is in another IP. How can I enable CORS on Espruino or why's happening that?

use response.writeHead() and write out the CORS header that way.

I do it in this code - https://github.com/SpenceKonde/AzzyProjects/blob/master/Animate/Version9.js

extend the res.writeHead and play around with the Access-Control headers

res.writeHead(200, {
'Content-Type': 'text/plain',
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept'
});

Let us know, if this works for you.
