If you’re experiencing issues with your website not displaying the most recent changes, it’s possible that your web server cache is causing the problem. Clearing your web server cache can help ensure that visitors to your site are seeing the latest version. In this tutorial, we’ll guide you through the process of clearing your web server cache.
What is a Web Server Cache?
A web server cache is a mechanism used to temporarily store data, such as HTML pages and images, to improve website performance. When a user visits a website, instead of fetching all the data from scratch, the web server first checks if it has a cached version of that data. If it does, it serves the cached version instead of generating the content again.
Why Would You Want to Clear Your Web Server Cache?
While caching improves website performance by reducing load times, it can also cause issues when changes are made to the website. For example, if you update an image on your site but visitors are still seeing the old image due to caching, clearing the cache will ensure they see the latest version.
Clearing Web Server Cache
Clearing your web server cache typically involves accessing your hosting control panel or using command-line tools. The exact method may vary depending on your hosting provider or server configuration.
1. Using cPanel
- Login to your cPanel account.
- Navigate to the “Advanced” section and look for “Cache Manager” or “Cache Settings”.
- Select your domain or website from the list.
- Click on “Purge All” or similar button to clear the cache for your website.
2. Using SSH and Command Line
- Connect to your server using SSH.
- Run the appropriate command to clear the cache.
This can vary depending on the caching software used on your server. Some common commands include:
For Varnish Cache:
$ varnishadm -T :6082 "ban req.http.host ~ example.com"
For Nginx FastCGI Cache:
$ curl -X PURGE http://example.com/some/page
3. Contacting Your Hosting Provider
If you’re unsure how to clear your web server cache or don’t have access to the necessary tools, contacting your hosting provider’s support team is a good option. They can assist you in clearing the cache or provide guidance specific to your hosting environment.
