- If MD5 validation is configured for a file on the origin server, do not enable the HTML optimization feature.
The HTML optimization feature changes the MD5 value of a file. After the file is optimized, the MD5 value of the file is no longer the same as the original file stored on the origin server.
- If the origin server has Gzip or Brotli compression enabled, HTML optimization does not take effect. DCDN directly returns compressed files to clients.
- If both HTML optimization and Intelligent or Brotli compression are enabled, HTML optimization does not take effect. DCDN only compresses files.
