Crossbar newbie question about browser support

[Zhou Chao]

I use crossbar.io with pyramid

I run pyramid on port 6543 and crossbar.io on port 8786

I already can communicate over websockets, so I want to comply old browser support

I already try these solutions

1. read  https://github.com/crossbario/crossbar/wiki/Browser%20Support
   
2. use https://github.com/gimite/web-socket-js/,  but it dont support wamp, I guess need DIY?
   
3. use longpoll by AutobahnJS, but error happen. 

XMLHttpRequest cannot load http://127.0.0.1:8786/lp/open. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:6543' is therefore not allowed access. The response had HTTP status code 501.

because cross origin

chrome developr console output:

AutobahnJS debug enabled 

trying to create WAMP transport of type: longpoll

longpoll.Factory.create 

new http_post request http://127.0.0.1:8786/lp/open {"protocols":["wamp.2.json"]} 2000

using WAMP transport type: longpoll 

OPTIONS http://127.0.0.1:8786/lp/open  

XMLHttpRequest cannot load http://127.0.0.1:8786/lp/open. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://127.0.0.1:6543' is therefore not allowed access. The response had HTTP status code 501. 

longpoll.Transport: could not open transport 0 

retrying in 1.4713375856010915 s 

I dont know how to solve this problem

PS. sorry for my bad english :)

No, that should work. I added that to Crossbar.io:

https://github.com/crossbario/crossbar/wiki/Flash-Policy-Transports

Note: I only tested this with recent Chrome/IE _forcing_ use of Flash.
We could need help testing this with say IE8/9+Flash10+ ...

Please file a bug against AutobahnPython .. this should work. But I need
more time to look into / track this down.
