I have some sites mysite1.com, mysite2.com,....mysiten.com
All mysite1-n.com using external javascript on myexternalsite.com/mainfile.js
I want,
if (mysite1-n.com) visitors come from www.google.com then will redirect to welcome.com
if (mysite1-n.com) visitors come from www.yahoo.com then will redirect to welcome2.com
if (mysite1-n.com) visitors come from www.anotherdomain.com then will call javascript on myexternalsite.com/file1.js and working using this script
And if (mysite1-n.com) visitors come from bookmark then will call javascript on myexternalsite.com/file2.js and working using this script
What sort of script should I be using on myexternalsite.com/mainfile.js ?
Thank's
