Hello everyone, I'm having this issue where APM-protected content fails to start APM session if called from an iFrame.  The access session starts at client request time as expected, and I can see t...

    So we did some more testing, and this is not going to work.

    We've worked with support and experimented with iRules to insert additional headers and cookies into the response, but the behaviour of CORS is that these are always going to be removed. And because APM relies heavily on cookies to function, it does mean that accessing APM-protected content from an iFrame will fail to work.

Hi,
I believe I came across a similar case, you may want to check this link,
https://community.f5.com/t5/technical-forum/apply-apm-to-an-iframe-the-content-cannot-be-display-in-frame/td-p/133029
The comment with the resolution, stated the below,

i found the way to prevent the dialog breaks out of the frame :

  1. go to the Access Policy -> Customization -> Advanced
  2. go to Access Profiles / / Access Policy / Logon Pages / Logon Page / logon.inc
  3. Search for if(self != top) { top.location = self.location; } and comment it out so it looks like this: //if(self != top) { top.location = self.location; }
  4. Save changes; Apply policy changes

      momahdy  I'm running BIG-IP version 16, logon.inc seems related to previous software versions and I have not found similar code in other ".inc" pages within advanced APM policy configuration menu.

        CA_Valli I tried a quick lab with v16.1.2 and can find it in line 140 this is using standard type not the modern type. in case issue still persist it would be very helpful to raise a case to support so that they can better inspect your environment specifically.
