Why does yslow identifiy my images, scripts and css as cookies?

Question

I am using yslow version 3.1.4

Answer 1

A cookie is sent with every request made to the host domain that matches the domain and path attributes that were specified when it was set with a set-cookie: response header.

When your browser issues a GET for print.css its request header will still contain a cookie: header if the domain & path match.

To prevent this see setting the path on cookie prevent it being sent in http static requests?.
