If you want to redirect to a different version of a file based on the time, this code is for you! Please read: Serve Alternate Content based on Time

Problem

Many webmasters use CGI scripts to do simple redirects based on the time of day. CGI incurs alot of overhead when used with SSI includes, even more so if the page is going to be called often.

Solution

Mod_rewrite provides system-variables for exactly this purpose. Using the lexicographic comparisons, we can do time-dependant redirects:

RewriteEngine On
RewriteBase /
RewriteCond %{TIME_HOUR}%{TIME_MIN} >0700
RewriteCond %{TIME_HOUR}%{TIME_MIN} <1900
RewriteRule ^index.html$ /index.day.html
RewriteRule ^index.html$ /index.night.html

This provides content for index.html so that requests done between 7am to 7pm are considered "day", and therefore get redirected to index.day.html, otherwise the page index.night.html is displayed.

Hacking and Hackers

The use of "hacker" to mean "security breaker" is a confusion on the part of the mass media. We hackers refuse to recognize that meaning, and continue using the word to mean someone who loves to program, someone who enjoys playful cleverness, or the combination of the two.
