Setting cache expiry times on your Content Delivery Network (CDN) is crucial for managing how long content is stored before being refreshed. Properly configuring cache expiry helps maintain content freshness while optimising performance and resource usage. In this guide, we’ll explain what cache expiry times are, why they matter, and how you can effectively set them on your CDN. Additionally, we’ll highlight how Lightyear Hosting can assist you with this process.
What Are Cache Expiry Times?
Definition of Cache Expiry Times
Cache expiry times, also known as Time-to-Live (TTL), define how long content is stored in a CDN’s cache before it is considered outdated and needs to be refreshed. This setting determines the duration for which cached content remains valid before a new request is made to the origin server for updated content.
How Cache Expiry Works
When a user requests content from your website, the CDN checks its cache. If the content is still within its expiry time, the CDN serves it from the cache. Once the expiry time is reached, the CDN fetches fresh content from the origin server and updates its cache.
Why Setting Cache Expiry Times Is Important
1. Content Freshness
Appropriate cache expiry settings ensure that your users see the most up-to-date content. This is crucial for sites that frequently update their content, such as news sites or e-commerce platforms.
2. Performance Optimisation
Optimising cache expiry times can enhance website performance by balancing the load between the CDN and your origin server. Shorter expiry times may reduce the load on the CDN, while longer expiry times can reduce server requests.
3. Cost Efficiency
Managing cache expiry can help control costs associated with data transfer and server load. By setting efficient expiry times, you can reduce unnecessary traffic to your origin server and optimise CDN usage.
4. Resource Management
Properly configured cache expiry times help in managing resources effectively, ensuring that the most relevant content is served while minimising server load and bandwidth consumption.
How to Set Cache Expiry Times on Your CDN
1. Access Your CDN Management Dashboard
Description: To set cache expiry times, start by logging in to your CDN provider’s management dashboard.
Steps:
- Login: Enter your credentials to access the dashboard.
- Navigate to Cache Settings: Locate the section for cache or caching rules.
Tip: Lightyear Hosting provides an easy-to-use control panel where you can manage your CDN settings, including cache expiry times.
2. Configure Cache Expiry Times
Description: Adjust the settings to define how long content should remain in the cache before it expires.
Steps:
- Select Cache Rules: Choose whether you want to set expiry times globally, for specific types of content, or on a per-file basis.
- Set TTL Values: Enter the desired TTL values for your content. These are typically set in seconds, minutes, or hours.
Recommendation: For most websites, a TTL of 5 to 30 minutes is common for dynamic content, while static content may benefit from longer TTLs.
Tip: Lightyear Hosting offers comprehensive documentation and support to help you configure these settings effectively.
3. Apply and Save Changes

Best Practices for Setting Cache Expiry Times
1. Tailor TTL Values to Content Types
Different types of content may require different TTL values. For instance, static assets like images and stylesheets can have longer TTLs, while dynamic content like news articles or product details may need shorter TTLs.
2. Test and Adjust
Regularly test and adjust TTL values to find the optimal balance between performance and content freshness. Monitor user feedback and website performance to fine-tune settings.
3. Use Cache-Control Headers
Implement Cache-Control headers in your HTTP responses to specify caching policies directly from your origin server. This allows you to control caching behaviour more precisely.
4. Consider Content Update Frequency
Set shorter TTLs for content that changes frequently and longer TTLs for content that remains relatively static. This approach helps optimise cache efficiency and server load.
