This reverts apache#8548 and instead directly calls HttpTransact::need_to_revalidate in TSHttpTxnCacheLookupStatusGet to ensure that an object which is a cache hit is indeed something ATS can return to the client. Fixes apache#8616

There was a problem hiding this comment.
Looks reasonable. The root cause is explained in #8616 (comment) .
It looks like with #8484, the need_to_revalidate revalidate function is no longer called before TSHttpTxnCacheLookupStatusGet is called, and thus the cache_hit_but_revalidate flag isn't set yet.

Fixing apache#8539 is easy to do in a common case, but it causing issues in corner cases. For now I'm going to revert the fixes for this and circle back around later to see whether this can be solved in a different way. This reverts the following commits: Revert "Commenting TSHttpTxnCacheLookupStatusGet need_to_revalidate (apache#8621)" This reverts commit 4678ae3 Revert "TSHttpTxnCacheLookupStatusGet: call need_to_revalidate (apache#8617)" This reverts commit 235c44a. Revert "TSHttpTxnCacheLookupStatusGet: handle cannot respond cases (apache#8545)" This reverts commit 080e236.

This reverts #8545 and instead directly calls
HttpTransact::need_to_revalidate in TSHttpTxnCacheLookupStatusGet to
ensure that an object which is a cache hit is indeed something ATS can
return to the client.
Fixes #8616
For Review:
This fixes the cache-request-method.test.py AuTest which is currently failing CI for master. Most of this change simply reverts #8545. The only real change is calling need_to_revalidate in InkAPI.cc in TSHttpTxnCacheLookupStatusGet.
