How to determine if a browser is cookie-enabled?

My problem is that I am trying to program an e-commerce web crawler. On some sites, I receive a ''browser not cookie enabled" page on the very first request/response. This leads me to believe that I need to stick a 'cookie' entry into the initial request so that the site can determine that the crawler is able to handle cookies.

Is this correct? Is there a generic entry a cookie enabled browser sticks in the request header on the initial request to show that it is cookie enabled?

I have poured over the http/1.1 standard and I can't find either the 'Cookie' or 'Set-Cookie' header entries anywhere. Is there somewhere else I should look?

Thanks in advance!
