I want to change the origin policy in chrome, how can I access it and modify it?
Many thanks
Are you talking about relaxing the same origin policy for file:/// urls? If so, I strongly recommend you set up a web server on your local machine and develop that way.
That said, you can run Chrome with this command line flag: --allow-file-access-from-files This will make all file:/// urls run in the same origin. The downside: any .html page you download and open could possibly open any file on your system and upload it to some server without you knowing. So you need to be more careful if you're doing this.
Besides file:/// urls you cannot change the same origin policy outside of APIs like CORS.
