PhantomJs Vs Selenium

[Tabish Matin]

Hey Guys,

Currently I am using Selenium for automation and scrapping. Everything working fine but it's bit slow and minor issues. My solution developed using C#.

I am planning to use PhantomJS as a backup thing but don't want to use Selenium to as part of it.

My Questions:

1. How can I implement keep alive session because I don't want to login again and again. It will login once and then wait for operation to come.

2. How can I pass dynamic task (operation) to that session. for e.g. Read value for specific textbox and then after few minutes read value from table.

Is this sort of thing possible to do with phantom JS without using selenium.

Thanks
