TCP_MISS_ABORTED/100 errors when uploading large files via squid proxy running on Red Hat Enterprise Linux 9

Issue

• Unable to upload files larger than 2M with squid. The procdure was working well with the same configuration in Red Hat Enterprise Linux 8. However, it started failing after migration to Red Hat Enterprise Linux 9.

  #curl -x localhost:3128 -X POST -F upfile=@/etc/squid/test2M http://10.0.0.2/upload.php -v
  Note: Unnecessary use of -X or --request, POST is already inferred.
