the local environment is wamp
apach2.4.33
the browser is Google 67.0.3396.99
apach has not set the configuration for http to automatically jump to https


what is the network path displayed by the browser developer tool when requesting http directly? See why it jumps?


found the reason, because
< meta http-equiv= "Content-Security-Policy" content= "upgrade-insecure-requests" / >
automatically escalated http's unsafe requests to https, so the requests all became https
