I am developing a single page Javascript application in MAMP. My JavaScript and HTML template files are getting cached between requests.

Is there a simple way to indicate in MAMP that I want to prevent http file caching? Possibly with a .htaccess file? Where do I place the .htaccess or modify the virtual host for MAMP on Mac?

Tried this? Should work in both .htaccess, httpd.conf and in a VirtualHost (usually placed in httpd-vhosts.conf if you have included it from your httpd.conf)

<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>

100% Prevent Files from being cached

This is similar to how google ads employ the header Cache-Control: private, x-gzip-ok="" > to prevent caching of ads by proxies and clients.

From http://www.askapache.com/htaccess/using-http-headers-with-htaccess.html

And optionally add the extension for the template files you are retrieving if you are using an extension other than .html for those.
