Can cloudflare cache be set to ignore all but a specific query string parameter? I can find things in the docs that allude to this being a possibility - but I cannot tell if it's part of the normal cache rules or else if it's something that requires cloudflare workers.
Example -
?var1=xxxx&var2=xxxx&var3=xxxx&var4=xxxx
Can I cache ONLY on differences say in var3?
