Disabling Caching with .htaccess

For our friends and fellow designers who would rather not have to perpetually clear browser cache while fine-tuning CSS, Actionscript, ads or procedural images, you might want to have a look at the following apache/.htaccess directive:

<filesMatch "\.(html|htm|js|css)$">
FileETag None
<ifModule mod_headers.c>
Header unset ETag
Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"
</ifModule>
</filesMatch>
