Caching Tutorial for Webmasters
If you examine the preferences dialog of any modern Web browser (like Internet Explorer, Safari or Mozilla), you'll probably notice a 'cache' setting. This lets you set aside a section of your computer's hard disk to store representations that you've seen, just for you. The browser cache works according to fairly simple rules. It will check to make sure that the representations are fresh, usually once a session (that is, the once in the current invocation of the browser).
Actual Htaccess Files from My Server
#### No https except to wp-admin -
# If the request is empty ( implies fopen or normal file access by a php script )
RewriteCond %{THE_REQUEST} ^$ [OR]
# OR if the request if for wp-admin or wp-login.php
RewriteCond %{REQUEST_URI} ^/(wp-admin|wp-login.php).*$ [NC,OR]
# OR if the Referer is https
RewriteCond %{HTTP_REFERER} ^https://www.askapache.com/.*$ [NC]
# THEN skip the following rule, basically all this does is force https or badhost to be redirected
# BUT because of the above 3 rewritecond's, this won't break poorly written admin scripts
RewriteRule .* - [S=1]
RewriteCond %{HTTPS} =on [OR]
RewriteCond %{HTTP_HOST} !^www.askapache.com$ [NC]
RewriteRule .* https://www.askapache.com%{REQUEST_URI} [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9} /(wp-admin/.*|wp-login.php.*) HTTP/ [NC]
RewriteCond %{HTTPS} !=on
RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

Preload flash .flv files into browser cache
How I was able to preload many flash flv and swf files on one of my clients sites that has a lot of online video and relatively small traffic. Their site visitors would usually watch 3-10 videos per visit and so to make the videos load almost instantly on every page I came up with a way to preload the top 10 .flv files and the swf flv player files as soon as the visitor successfully started watching the 1st video. Of course I also setup .htaccess caching on the server so that once they downloaded the files into their cache they would never request them from the server again. I was having fun with this so its pretty funky and uses some really cool combinations of javascript, swf preloader from xml, css classes to help automate it all..

mod_rewrite Fix for Caching Updated Files
Web Developers sometimes use file.ext?v=004 as a version control system to force visitors to use updated files. This is terrible. Instead link to apache-003.css and set it to be cached forever. When you change the file you just change the links to apache-004.css. That eliminates millions of bandwidth and resource robbing If-Modified-Since requests. You only need Apache with mod_rewrite, and 1-10 minutes!
