This project was designed to add new functionality to LuckyAssetManager (https://github.com/luckyllama/LuckyAssetManager). In LuckyAssetManagerContrib implemented 2 custom processor:
SelectPathProcessor (processor for choosing pre-minified assets with file extensions
*.min.css in release mode) and
FinalProcessor (responsible for replacement relative paths in CSS-files, combining and caching assets), and new improved HTTP-handler (supports browser caching and ETags).
Also available in nuget:
