The SSL site has been changed to the "htpps ~" site. I want to display the site of iframe.
Could you tell me how to display it?

Error message

At the time of "http ~" before SSL conversion, the external site could be displayed in iframe without any problem, but it was not displayed when SSL was converted.
It is pure white and nothing is displayed.

Applicable source code
<iframe src = "http://www.hoge.com/index.html" frameborder = "0" width = "100%;">
Tried

The URL of the external site to load was omitted from "http:" and specified with "// www ~", but it was not displayed.
Without "http:", the URL seems to be specified as "https:".

Once I tried to load an empty page on the internal site with an iframe and then redirect to display the external site, it didn't work at all.

Supplemental information (FW/tool version etc.)

Isn't it possible to load an "http" external site in an iframe in the first place?

  • Answer # 1

    Iframes that are always used within SSL will feel like NG with mixed content if the address in the iframe is not SSL-enabled.

  • Answer # 2

    I think I should be able to display it, but I came up with a possible cause and I will write it.

    Did you set the CSP header when the server was turned into SSL?
    If CSPframe-srcis not set, it will not be displayed.
