Explains why CSS updates fail to appear after ColdFusion deployments, walking through every caching layer involved: browser cache, ColdFusion's template cache and Trusted Cache, the cfcache tag, web server caching (IIS/Apache), and CDN/proxy caches. Provides CFML code for setting cache headers, programmatically clearing ColdFusion's template cache via ServiceFactory, flushing cfcache, and implementing cache-busting through query string versioning or filename fingerprinting using getFileInfo(). Includes a debugging checklist and deployment checklist for enterprise ColdFusion teams, and promotes Lucid Outsourcing Solutions as a consulting partner for these problems.

Why do my CSS changes not show up after deploying a ColdFusion application?
Multiple independent caching layers each store the old stylesheet: the browser cache, ColdFusion's compiled template cache, ColdFusion's Trusted Cache setting, the cfcache tag's rendered page output, the web server (IIS or Apache) static file cache, and a CDN or proxy edge cache. Clearing only one layer, such as the browser, leaves the others serving stale CSS to other users. Track deployment gotchas like multi-layer caching issues on daily.dev while hardening your release process.
How do I programmatically clear the ColdFusion template cache after a deployment?
Use ColdFusion's Java ServiceFactory API by calling createObject("java", "coldfusion.server.ServiceFactory").getCacheService(), then invoke clearTrustedCache() and clearQueryCache() on the returned object. Placing this in a protected deployment endpoint that a CI/CD pipeline calls lets every deployment clear the cache automatically without restarting the server, keeping uptime unaffected. Developers automating ColdFusion release pipelines can follow ongoing deployment practices on daily.dev.
What is the difference between query string versioning and filename fingerprinting for CSS cache busting?
Query string versioning appends a ?v= parameter (like a build number or timestamp from application.cssVersion) to the stylesheet URL, which is simpler to implement, while filename fingerprinting embeds the version directly into the filename itself, such as main.1748793600.css, offering stronger cache isolation since CDNs and proxies treat it as an entirely different resource. Fingerprinting requires a URL rewrite rule in web.config or .htaccess to map the fingerprinted name back to the real file.
