Question

Im trying to login to google using php curl. I found this post:

Login to Google with PHP and Curl, Cookie turned off?

It worked great. But my objective is to stay logged in after posting the login request. I want to maintain the browser session so when i open gmail or any google service in new tab it should stayed login.

Is it possible? If yes, any help or suggestion will be highly appreciated.

Please let me know if my question is not clear enough.

Thanks!
