How does Query String Sort make my website faster?
When set to “On”, this feature enables query strings to be sorted before they hit CloudFlare’s cache for increased cache hit rates.
Today, we treat URLs query strings that are in different orders as separate files in the cache. This mean that if one user requests:
/video/48088296?title=0&byline=0&portrait=0&color=51a516
And another user requests:
/video/48088296?byline=0&color=51a516&portrait=0&title=0
We will go back to the origin, even though we have the file in our cache.
Query String Sort will sort the query strings before they hit our cache resulting in a higher cache hit rate.
