Caching Tutorial for Web Authors and Webmasters

by 23 others, 1 comment
A Web cache sits between one or more Web servers (also known as origin servers) and a client or many clients, and watches requests come by, saving copies of the responses — like HTML pages, images and files (collectively known as representations) — for itself. Then, if there is another request for the same URL, it can use the response that it has, instead of asking the origin server for it again.

How To Optimize Your Site With HTTP Caching | BetterExplained

by 2 others
Caching is a great example of the ubiquitous time-space tradeoff in programming. You can save time by using space to store results. In the case of websites, the browser can save a copy of images, stylesheets, javascript or the entire page. The next time the user needs that resource (such as a script or logo that appears on every page), the browser doesn’t have to download it again. Fewer downloads means a faster, happier site.

Surviving 100,000 instant Visitors on a Budget

(via)
Last Sunday I casually wrote a post about the most common pitfalls in photography. I had written the post a long time ago, but I never put it on this site. The story ended up on the front page of Digg, stayed there for nearly 12 hours and was picked up by a bunch of secondary sources, resulting in 100,000 Visitors within a day (most of them within the first 12 hours). Trying to keep my server up and alive, I learned a lot about what it takes to keep the server alive, hence I decided to slide a non photography related post in, hopefully giving everyone who finds themselves in a similar situation some points to consider.
