In this week’s episode of Two-Minute Tech Tuesday, we'll talk about Hitch. Hitch is an open-source TLS proxy that Varnish develops and maintains. It can be used to terminate TLS, which is especially useful if you're using Varnish Cache.

HAProxy’s proxy protocol has been supported as part of Varnish 4.1 for a few months now. The proxy protocol's main purpose is to transport client connection information from the originating source requesting the connection. It adds a small header about the origin connection.
