Golang缓存是否同时请求URL的“ http / https”版本?

I am currently working with the net/http package to make a request by passing the URL from the command line but what I discovered was that : A cache is made for the request to both http/https version of a URL I am testing with

I have tried reading about the package net/http Do method https://golang.org/pkg/net/http/#Client.Do

httpResponse, err := c.Do(request)
    if err != nil {
        fmt.Println("An error occurred from the response ", err.Error(), URL)
        os.Exit(100)
    }

Scenario 1: go run web/webClient/webClient.go https://www.mtsoukalos.eu/

Result:

An error occurred from the response  Get https://www.mtsoukalos.eu/: x509: certificate signed by unknown authority https://www.mtsoukalos.eu/
exit status 100

Scenario 2: go run web/webClient/webClient.go http://www.mtsoukalo.eu/

An error occurred from the response  Get https://www.mtsoukalos.eu/: x509: certificate signed by unknown authority http://www.mtsoukalos.eu/
exit status 100

The expected result of the URL in Scenario 2 should be http://www.mtsoukalos.eu/ but I still get https://www.mtsoukalos.eu/.

Can you help me understand why it is happening this way?
