I’m having trouble coming up with a good name for my latest WordPress plugin so I thought I’d crowd source it. 🙂
My other WordPress-powered site, FinalGear.com, receives very large traffic spikes. I used to just run WP Super Cache to prevent the site from going down but Apache would still actually die under the load even though it was just serving static content. Since the site has no comments or other often changing content, the easiest solution at the time was just to throw a reverse proxy called Varnish in front it with a decent cache time (5-10 minutes per page). I’ve since switched from Apache to nginx which solves that issue but it’s still easiest to just leave Varnish there.
Varnish is set up to ignore cookies on the front end of the site. That means I get served the exact same version of the site that you (a guest) sees — no admin bar, no post edit links, and so forth. Getting to the admin area is easy thanks to an absolutely positioned hidden link in the bottom left of the site (hover over it, you’ll find it) so lack of an admin bar is no problem for me.
