Nginx+Lua is a self-contained web server embedding the scripting language Lua. Powerful applications can be written directly inside Nginx without using cgi, fastcgi, or uwsgi. By adding a little Lua code to an existing Nginx configuration file, it is easy to add small features.

Tengine is a web server originated by Taobao, the largest e-commerce website in Asia. It is based on the popular Nginx HTTP server and has many advanced features. Tengine has been proven very stable and efficient on the top 100 websites, including taobao.com and tmall.com.

To illustrate one of the ambiguities in the law, I’ve implemented a tool which tracks site visitors almost as effectively as cookies (or similar technologies such as Flash Objects or Local Storage), but which must necessarily fall into one of the larger grey areas.

Mongrel2 is an application, language, and network architecture agnostic web server that focuses on web applications using modern browser technologies

The mockjax plugin is a development and testing tool for intercepting and simulating ajax requests made with jQuery with a minimal impact on changes to production code.

A web page is an ecosystem where multiple objects contribute to the web page content, and as a result to its slowness or even unavailability. Some of the slowness can be due to poor server performance but at times is due to DNS related issues.

PHProxy is a web HTTP proxy programmed in PHP meant to bypass firewalls and access otherwise inaccessible resources (i.e. blocked websites). If the server this script is run on can access a resource, so can you!

For as long as I remember, HTTP cookies have been vilified as a grave threat to the privacy of online browsing; wrongly so. That said, the mechanism itself is a very interesting cautionary tale for security engineers - and that will be the theme of today's feature.

URL Design is a complex subject. I can’t say there are any “right” solutions — it’s much like the rest of design. There’s good URL design, there’s bad URL design, and there’s everything in between — it’s subjective.

to match Google's page load times you have to cheat on the tcp slow-start algorithm. It appears that stretching the parameters a little bit is fairly common, but Google and Microsoft push it a lot further than most.
