Server caching is a common practice to boost a website's performance by storing and serving rendered pages to subsequent visitors. However, certain dynamic pages or URLs require real-time data and shouldn't be cached. This guide outlines ways to disable server caching for specific URLs or pages on Rapyd Hosting, which by default doesn't implement page caching. The guide also helps you navigate through additional caching layers that might be introduced by you or third-party plugins.

Understanding the Need to Bypass Cache for Specific URLs

Certain web pages like those displaying real-time stock quotes, user dashboards, or dynamic forms need to show accurate and updated information. Caching such pages can result in outdated or incorrect data being served to users.

Methods to Disable Server Caching

If you've implemented caching mechanisms such as CDN, browser, or application-level caching, you can bypass them using:

  • Headers: Utilize cache-control headers to specify caching behavior.

  • Configuration Files: Modify settings in .htaccess or other server configuration files.

Step-by-Step Guide

Using Cache-Control Headers:

  1. Identify the URL or page you want to exclude from caching.

  2. Set the Cache-Control header in your server or application to 'no-store, no-cache, must-revalidate, post-check=0, pre-check=0'.

  3. Also, set the Pragma header to 'no-cache' and the Expires header to a past date.

Using .htaccess (For Apache servers):

  1. Locate your website's .htaccess file, usually found in the root directory.

  2. Insert the following code, replacing /path/to/specific-page with your specific path:

<Location /path/to/specific-page> Header set Cache-Control "no-store, no-cache, must-revalidate, post-check=0, pre-check=0" Header set Pragma "no-cache" Header set Expires "Thu, 1 Jan 1970 00:00:00 GMT" </Location>

Verifying the Configuration

After implementing the changes:

  • Use browser development tools to inspect the headers for your specific URL/page. Ensure that the Cache-Control, Pragma, and Expires headers are set as intended.

  • Test the functionality of the page to confirm that it delivers real-time and updated content.

Conclusion

While caching can enhance performance, it's not universally beneficial. By adhering to the methods laid out above, you can selectively disable caching for particular URLs or pages, thereby ensuring accurate and real-time content delivery. Remember, Rapyd Hosting doesn't cache pages by default, but if additional caching layers or third-party plugins have been employed, managing them appropriately is crucial for delivering an optimal user experience.
