Page caching is really good…
Most busy WordPress websites make use of some page caching plugin to ease processing load off servers and please site visitors with faster page loads. These WordPress caching plugins cache entire pages for serving up quickly.
…except when it isn’t
Sometimes, however, cached pages cannot be used. This is common for:
- Membership sites, where user-specific content would make cached pages incorrect for most users.
- Sites with rapidly updated page content, where cached pages would not keep up with visitors’ expectations.
- Sites presenting unique content based on visitors’ location, browser, and other personal variables.
