Servicenow Iframe issues

[Devtesting123]

Hi 

I'm trying to load Servicenow as an iframe in a website but im getting an error.

Looking at the browser console logs i see this error *** WARNING *** GlideAjax.getXMLWait - synchronous function - processor: SysMessageAjax.

The page doesn't seem to cache, even though I'm logged into my servicenow instance in another browser tab

@Devtesting123 What is the business requirement? Iframe has cross scope restrictions, that could be the issue.

GlideAjax.getXMLWait could be due to any Global script running on load of instance.

My thought

• ServiceNow restricts embedding its pages in external iframes due to security headers like X-Frame-Options: SAMEORIGIN, which blocks loading in cross-origin iframes
• the risk is shared here (Why you should never use external iFrames - and the one exception to this rule )

But please check these links

Specify URL allow list for cross-origin iframe communication (instance security hardening)

Try using getXML() in GlideAjax.
