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.

In this week’s episode of Two-Minute Tech Tuesday, we'll talk about the PROXY protocol. The PROXY protocol transports client connection information across multiple proxy servers.
