Using a simple softlink (with the same hosting server) and a robots.txt we can bring the manageability to the same level as method 1.

I think the most optimized way of handling images/css/js is having another domain. Can you point any negative point (apart from manageability, we can do it easily with a softlink and robots.txt) with method 3?

Thanks for the reply.
