Seems that my issue is similar to - https://serverfault.com/questions/1104330/squid-cache-items-behind-basic-authentication

You are facing up to two problems:

1. Some authenticated responses are not cachable by Squid. Please share HTTP headers of the response in question.


FYI, those can be obtained by configuring squid.conf with

  debug_options 11,2

2. TCP_MISS_ABORTED/502 errors may delete a being-cached response. These can be bogus errors (essentially Squid logging bugs) or real ones (e.g., due to communication bugs, misconfiguration, or compatibility problems). I recommend adding %err_code/%err_detail to your logformat and sharing the corresponding access.log lines (obfuscated as needed).

Sharing (privately if needed) a pointer to compressed ALL,9 cache.log while reproducing the issue using a single transaction may help us resolve all the unknowns:

HTH,
