I ran across the concept known simply as “Microsoft Free Fridays”. Originally I belive it was written as an apache module, but thats too much work. On the other hand I like mod_rewrite — so I shall use that. So starting from now on most all of my websites will be MSIE Free Fridays.
mod_rewrite code for thoes intrested:
<br />
RewriteCond %{TIME_WDAY} ^5$<br />
RewriteCond %{HTTP_USER_AGENT} MSIE<br />
RewriteCond %{HTTP_USER_AGENT} !Opera<br />
RewriteCond %{HTTP_USER_AGENT} !Oregano<br />
RewriteRule ^.*$ http://www.getfirefox.com [R=302,L]<br />
