So client_delay_parameters affects speed of an end-user uploading to squid (i.e., client requests and uploads) and delay_paramaters affects speed of squid downloading from a server? Does client_delay_parameters affect speed of transferring a file from squid to an end-user (e.g., when serving cached content)? If a file that is cached is requested by an end-user (i.e., not retrieved from a remote web server), does delay_paramaters have any effect? -Nick
