Understanding Caching

File caching is an essential technique for improving the speed of website loading and reducing server load. It involves storing copies of files in the browser or proxy server cache for quick reuse.

Recommended Cache Durations

Cache durations should be carefully selected to balance content freshness with performance. For static resources like images, CSS stylesheets, and JavaScript scripts, a long duration (typically one year) is recommended as long as these files do not change often. For dynamic or frequently updated content, shorter durations or cache validation strategies are preferable.

Types of Files to Cache

It is advisable to cache file types that do not change frequently, such as PDF documents, images (JPEG, PNG, SVG), video files, external CSS, and JavaScripts. These files benefit from extended caching due to their generally large size and infrequency of changes.

Cache Configuration

Cache configuration can be done via the ".htaccess" file for Apache servers, or the "nginx.conf" file for NGINX, using directives to specify cache durations by file type. Using HTTP headers like "Cache-Control" and "Expires" helps control how resources are cached.

Impact on Performance and SEO

A good caching strategy significantly improves page loading speed, which positively contributes to user experience and SEO. Search engines favor sites that load quickly, which can positively influence page rankings.

Best Practices

Incorporate versions or digital fingerprints (hashes) in the filenames of static resources to manage updates without interfering with the existing cache. This allows for aggressive caching while ensuring that users receive the most recent version of the resources after they are updated.

Server-Side Caching

Server-side caching involves using an intermediary cache, such as a reverse proxy server or a CDN (Content Delivery Network), to store copies of resources. This reduces the load on the origin server and allows for geographically dispersed access for faster user reach.

Cache Validation

For resources that change regularly, cache validation is an alternative to full caching. Instead of serving a potentially outdated cached copy, the browser or proxy checks if the resource has changed since the last request using HTTP headers like "ETag" or "Last-Modified".
