We are using CustomCacheKey
rules for API requests. To avoid spamming the backend when prefetching, we want to receive 412
for non-cached requests. xdn_prefetch=1
query parameter is sent within API requests as per documentation.
Everything works as expected when cache()
is called without CustomCacheKey. — responses are cached on edge and requests with xdn_prefetch=1
are returning 200
The problem is as follows:
Our key
looks like this:
key: new CustomCacheKey()
.addHeader(“x-something”)
.addHeader(“x-something2”);
With such code, prefetch requests never return 200
I’ve tried to add .excludeQueryParameters("xdn_prefetch")
manually to the cacheKey but it didn’t work.
