I think you misunderstand what "proxy" means. Nginx primary design focus
as a web server like Apache. So proxied traffic is a special activity
Squid is a proxy. So by definition everything going through Squid is
<http://www.squid-cache.org/Doc/config/read_timeout/> controls the
timeout for individual read(2) operations on a connection which is active.
<http://www.squid-cache.org/Doc/config/write_timeout/> controls the
timeout for individual write(2) operations on a connection which is active.
controls the timeout for connections in idle state between requests.
Other timeouts control specific actions like DNS, route selection,
connect(2), or client connection activities.
