After page optimization is enabled, it automatically deletes annotations and repeated white spaces in html, which effectively removes redundant content on the page, reduces file size and improves the efficiency of accelerated delivery.
If the files of origin server are configured with MD5 validation mechanism, please do not enable such feature. When CDN executes page optimization, the MD5 value of the file is changed, and the MD5 value of the optimized file is different from the MD5 value of the file of the origin station.
