In Squid? HTTP, plus HTTP proxying of FTP and Gopher. Internally it
also caches DNS lookups for it's own use to improve performance.

Yes, except for SSL which cannot be cached as it is only tunneled via
proxies as it is encrypted with the actual requests and content only
visible to the browser and the origin server.
