Use cookie-free domains - subdomain solution not working

Question

I'm trying to optimize an html webpage, and one of the suggestions from yslow is:

Use cookie-free domains There are 11 components that are not cookie-free

So I followed one of the standard solutions I've seen and created a subdomain static.mysite.com and put the images there.

But I'm still getting the exact same problem -- a cookie is still being delivered with each image, and same yslow message.

So how do I get this subdomain to be cookie free?

Answer 1

If you are using subdomain for cookie-free delivery then your main page has to use www prefix.
