To Install -- Non-PmWiki websites
Files- 
	iframe_host.js & iframe_guest.js
	(You should not need to modify these files for typical use.)
	
    >> You will need a reference in your hosting page's html to the iframe_host.js 
		e.g. <script src="iframe_host.js"></script>
		
If your host page and guest page are both on 
- the same domain (and subdomain), 
- the same port (e.g. 443),
- and the same protocol (e.g. https)
THEN:		
    >> iframe_host.js and iframe_guest.js must be in the same directory.
    >> the <iframe> tag in your html needs: class="BridgeFrame"
		e.g. <iframe src="guest.html" class="BridgeFrame" ></iframe>
		
Otherwise:
    >> the guest page MUST include a reference to a copy of iframe_guest.js 
	   (best if on the same server as the guest page.)
    >> the <iframe> tag in your html needs: class="BridgeFrame"
	>> you may wish to add crossorigin="anonymous" as an attribute as well
		e.g. <iframe src="guest.html" class="BridgeFrame"  crossorigin="anonymous"></iframe>
		
	
	
If the first method fails, even with same domain,port & protocol then try the second method.
