Auto login to social networks

Hi all,

    I am using omniauth and devise gem to login into twitter, facebook and linkedin sites.

Now when i click the link /auth/twitter it redirect to the login page of twitter of it will show my homepage if i logged in already.

What i want to do is when i click a url it should redirect me to my twitter home page(if i logged in ) or it should check the username and password which i saved in my local table siteaccounts(same twitter credentials) and logged in to my twitter home page instead of prompting me the log-in page of twitter.

Is it possible? if possible please guide me how to achieve it.
