6.1.3 Notes
The <iframe> tag is used in the custom UI tab. Due to this, if you try to display a Web page by using a property such as window.location.href when X-Frame-Options is specified for that Web page, you will not be able to display the Web page.
In this case, action is needed on the part of the website providing the Web page to allow access from JP1/IM.
- Example of a specification
X-Frame-Options ALLOW-FROM <URL-of-JP1/IM>
