Summary of Nginx Bandwidth Control methods

There is an old project that provides the file download function through Squid and uses delay_parameters to implement bandwidth control. The problem is that I don't want to convert Squid, so I figured out whether similar functions can be found in Nginx.The good news is that Nginx provides limit_rate and limit_rate_after. For example:Location/download /{Limit_rate_after 500 kb;Limit_rate 50 k;}It means that after the download reaches 500 KB, the us
