Full page output (relatively static pages)

I wrote couple of weeks ago on dangers of bad cache design. Today I’ve been troubleshooting the production down case which had fair amount of issues related to how cache was used.
The deal was as following. The update to the codebase was performed and it caused performance issues, so it was rolled back but […]
