I'm facing cross-subdomain / port problem with Socket.io. In example in Opera, when I disable Flash Socket.io automatically fallback to JSONP - and that's not good (XHR is way better).
I'm using now test subdomain, let's call it test.example.com. I tried many solutions.
http://data.test.example.com:80
http://test.example.com:8000
http://example.com:8000
None of solutions worked. Any hints? Maybe should I use nginx as reverse proxy? Something like http://test.example.com/data/
?
