Module: Vidibus::AssetCacheBuster

Defined in:
lib/vidibus/asset_cache_buster.rb,
lib/vidibus/asset_cache_buster/version.rb

Overview

Rewrite cache buster for assets. To get this solution working, it is required to add some configuration to your apache2 VirtualHost:

# Remove timesstamp from versioned static javascripts, stylesheets, and images. # This requires a change in Rails so that assets will be included as image.12345.jpg RewriteEngine on RewriteRule ^/(javascripts|stylesheets|images)/(.+).(.+).(js|css|jp?g|gif|png)$ /$1/$2.$4 [L]

This rewrite does not support SSL. Maybe Apache2 config should be improved…
