Since this is on Hacker News and reddit...

• No, I don't distribute my résumé like this. A friend of mine made a joke about me being the kind of person who would do this, so I did (the link on that page was added later). My actual résumé is a good bit crazier.
• I apologize for the use of _t in my types. I spend a lot of time at a level where I can do that; "reserved for system libraries? I am the system libraries".
• Since people kept complaining, I've fixed the assignments of string literals to non-const char *s.
• My use of type * name, however, is entirely intentional.
• If you're using an older compiler, you might have trouble with the anonymous unions and the designated initializers - I think gcc 4.4 requires some extra braces to get them working together. Anything reasonably recent should work fine. Clang and gcc (newer than 4.4, at le

Redirect: Temporary and Permanent

Source

What is an HTTP Redirect?

HTTP redirection, or URL redirection, is a technique of pointing one domain or address to another. There are many uses for redirection, and a few different kinds of redirection to consider.

As you create content and administrate servers, you will often find the need to redirect traffic from one place to another. This guide will discuss the different use-cases for these techniques, and how to accomplish them in Apache and Nginx.
