ASP.NET Core - VersionedAssets
VersionedAssets is middleware and taghelper for easier integration with CDN configured for origin pull. TagHelper creates asset urls with content version hash burned in url (for cache busting). Middleware handles requests comming from CDN and sets caching headers acordingly.
Following example assumes your CDN is configured with origin pull to base url
http://[your.site]/static.
TagHelper generated url: http://[your.cdn]/[version-hash]/bundles/app.js
Origin pull url: http://[your.side]/static/[version-hash]/bundles/app.js

loggerFactory.AddConsole(LogLevel.Debug);
// respond to cdn origin pull asset requests in the form /static/[hash]/*
