Hello,
After a few pairs of HTTP Get and Response, actually for different
clients to retrieve data, over the same persistent upstream
connection, Squid(3.1.11) may send one RST+ACK, following by a few
RST's with the same sequence number as RST+ACK. In some other cases,
Squid gracefully closes the upstream connection by initiating a
FIN+ACK packet. I guess Squid has some management procedure to
distinguish these cases... then what are the approaches?
RST or FIN as per the TCP specifications. Basically RST in errors.
When a client disconnects and the server connection cannot be re-used.
When client disconnects and object is not cacheable. When excess data is
pushed into the link by the server. When the server replies with invalid
response.
