(Optional) Recommended Configurations

After adding an acceleration domain name, configure cache rules, smart compression, and secure acceleration to improve the cache hit ratio, optimize the acceleration effect, and enhance security.

Improving Cache Hit Ratio and Optimizing the Acceleration Effect

Scenario

Configuration Item

Description

The cache hit ratio is low and the acceleration effect is not obvious.

Cache Rules

Set a proper cache TTL and priority for different resources to improve the cache hit ratio, reduce the origin pull ratio, and relieve the pressure on the origin server.

Notes:

  1. The cache rule priority is an integer ranging from 1 to 100. A greater number indicates a higher priority.
  2. If you modify or add a cache rule, purge the cache of the corresponding resource.
  3. Set the cache TTL of dynamic resources to 0, so dynamic resources are not cached. Otherwise, access exceptions may occur.
  4. Check the cache settings on the origin server. If no-cache, private, or no-store is configured for a resource on the origin server and Origin Cache Control is enabled on the CDN console, CDN cannot cache the resource. CDN needs to pull the resource from the origin server each time it is requested. This does not achieve acceleration.

Range Requests

Configure range requests to accelerate distribution of large files during origin pull and reduce bandwidth consumption.

  • Range requests are enabled by default for download acceleration.
  • Check whether the origin server supports the Range header.

Smart Compression

Compress static content on your websites to reduce the file size, speed up file transfer, and save bandwidth.

  • Smart compression includes gzip compression and Brotli compression. The performance of Brotli compression is 15% to 25% higher than that of gzip compression.
  • With smart compression, CDN automatically compresses .js, .html, .css, .xml, .json, .shtml and .htm files.

URL Parameters

Ignore URL parameters to improve the cache hit ratio and speed up content distribution.

  • If resources do not change with URL parameters, ignore the URL parameters.
  • If resources change with URL parameters, retain the URL parameters.

Improving Website Security

Scenario

Configuration Item

Description

Improving security performance

HTTPS

Configure an SSL certificate to improve the domain name security.

Access Control

Identify and filter visitors to restrict their access and improve CDN resource security.
