Unable to embed Jenkins page into an iframe. How to fix it?

From the Jenkins version 1.532 and later, the Jenkins page is not displayed in an iframe.

Do you need a way to permit Jenkins to be visible in selected iframes? Here you go.

To configure X-Frame-Options:

If you try to load content into an iframe and the X-Frame-Options header is set to SAMEORIGIN, then the content loading is prevented. To override the default X-Frame-Options header settings, you have to perform the following:

• You need to have the Jenkins plugin installed to configure the X-Frame-Options. You can download the plugin from https://wiki.jenkins-ci.org/display/JENKINS/XFrame+Filter+Plugin.
• You must have Jenkins administrative privileges to do this. On the Jenkins Configuration page, in the XFrame Filter Configuration section, enter the value for X-Frame-Options Options as ALLOW-FROM <ctf domain name>.

  For example, on the http://jenkins.maa.relenghub.collab.net/jenkins/configure page, enter ALLOW-FROM http://forge.collab.net for X-Frame-Options Options.

  Now, the page can only be displayed in a frame on the specified origin.
