table.blog { border-collapse: collapse; } table.blog td { border: 1px solid black; padding: 5px; } In the previous article in this caching series, we looked at the benefits of microcaching – caching dynamic content for very short periods of time – which sometimes leads to very significant performance improvement. In this article, we’ll consider another aspect of caching, that of cache placement, and we’ll look at strategies for dealing with slow cache storage. Selecting a Cache Location NGINX can manage multiple cache locations, each mapped to a different filesystem location, and you can configure NGINX to choose which cache to use on a per-request basis. In the following sample configuration, the proxy_cache_path directives create two caches, ssd_cache and disk_cache, mounted on the local directories /mnt/ssd/cache and /mnt/disk/cache respectively. The map directive inspects the request URL and selects disk_cache for all requests that appear to [ more… ]
