It is hard to work with whitelists (on *any* proxy, not just squid), because you have to whitelist the domain and all required domains (for example, for yahoo.com you will need yahoo.com and yimg.com). You will have to deeply explore the sites to whitelist, using firebug or similar to get what sites you need to whitelist in order to get them working correctly. Ildefonso.
