You are misunderstanding what is going on. Squid is simply delivering a 
cached response.

Either the exact original response, or with some updated headers 
supplied *by the server* during revalidation.

The log entry on your earlier post indicates there was _no_ server 
contact. So nothing was changed. Period.

That means what came out of cache was the previously cached response 
with original headers and formatting.

BTW: you should remove the ignore-must-revalidate. Squid current 
releases can only cache private responses IF revalidation is enabled.

The squid logs you presented earlier showed that the reply was a HIT, 
with *no* server connection made. So you cannot have got a packet 
capture when no TCP packets existed.

What you are seeing below could be another transactions response, or the 
response to some other request which did not get a gzip encoded
