Hello,
We are setting up some filtering on our APIs and I had a question about taking advantage of Query String Sort: https://blog.cloudflare.com/increasing-cache-hit-rates-with-query-string-sort/
Take these two examples of multi selecting colours as a query parameter.
/my/api?colour=red,blue
This sample we use a comma separated list of options, this has now split the cache. I can’t see how Cloudflare could sort this because to them red,blue
is just a string and they can’t change the order incase that order means something to the API. This makes is less cacheable but keeps character count down.
/my/api?colour=red&colour=blue
This way I believe Query String Sort can work because it knows they are the same parameter but it can now be sorted alphabetically to ensure there is only one cache entry. However this also means a lot larger URL - which could run over the maximum size limit.
Personally I think /my/api?colour=red&colour=blue
this option works, but I was just wondering if anyone had any comments here. I could not find any examples.
Thanks
Robin
