Dear Wiki user,

The following page has been changed by RichBowen:

New page:
= Redirect based on time of day =

== Problem: ==

You wish to serve different content depending on what time of day it is

== Recipe: ==

{{{
RewriteEngine on
RewriteCond   %{TIME_HOUR}%{TIME_MIN} >0700
RewriteCond   %{TIME_HOUR}%{TIME_MIN} <1900
RewriteRule   ^/foo\.html$             /foo.day.html [PT]
RewriteRule   ^/foo\.html$             /foo.night.html [PT]
}}}

== Discussion: ==

This ruleset will rewrite ''/foo.html'' to ''/foo.day.html'' between 0700 (7am) 
and 1900 (7pm), and will rewrite it to ''/foo.night.html'' the rest of the 
time. The RewriteCond causes the following RewriteRule to be skipped if the 
condition is not met, which is how we end up with an ''if ... else'' kind of 
syntax.

= Serve a contest page during a contest =

== Problem ==

Serve a contest page during a contest, but don't bug people with it more than 
once a day.

== Recipe ==

{{{
RewriteCond %{TIME} > 20050701080000
RewriteCond %{TIME} < 20050705170000
RewriteCond %{HTTP_COOKIE} !frontdoor=yes
RewriteRule ^/index\.html$  /contest.html \
        [R,CO=frontdoor:yes:.apacheadmin.com:1440,L]

}}}


== Discussion ==

If the date is between the two values (8am on July 1 and 5pm on July 5) and if 
they haven't already come through the front door, redirect /index.html to 
/contest.html and set a cookie for a day so that they don't have this happen 
again until tomorrow.
