You cannot purge something which is not in the cache.

NP: PURGE always says success if the object is not cached at the end of
the processing.

Weird. 0 is not bigger than 64KB. That is definitely a bug somewhere in
there.

The above mistake causes Squid to generate a 502 itself.

The 502 which was generated by your Squid is not being cached.
