I know how to provide URL to Salesforce.com instance with embedded login details by using this structure:
https://servername.com?pw=qwerty&un=myname%40example.com
Now the question is how to provide URL with login details to VF page? Could it be achieved using similar URL structure?
My VF page URL is something similar to this:
https://servername.com/apex/VF_Page?param=true

Possible Suggestion/Solution #1
It is possible to do by including a startURL parameter.
https://login.salesforce.com/?pw=qwerty&un=myname%40example.com&startURL=%2Fapex%2FVF_Page%3Fparam%3Dtrue
