Multiple-site configuration for Varnish Server
Recently, I started looking into building a Varnish server that could handle multiple websites, possibly running multiple frameworks. I knew that it was possible to include extra VCL’s based on hostname as seen on the Varnish Software blog, but when I tried to implement that in my config, I kept on getting errors.
Installing Varnish 3 on CentOS 7
Oddly, there isn’t a lot of information on installing Varnish 3 on CentOS 7. There’s well-written instructions on the official site for CentOS 5⁄6, but for 7, it seems like you’re stuck with Varnish 4 (from the epel-release repository), especially if you’ve searched around and found forum threads like this one.
