Hi all - long time reader, first time poster!
I’m attempting to introduce a Content Security Policy and it seems to have been cached 
I was initially using a trigger on page access to set the HTTP header, but the CSP declaration on the page wasn’t changing even when turning the trigger off.
Have since tried using a global variable and it still seems to be stuck no matter what
Global variables :: Squiz Documentation (Matrix)
Any help would be appreciated, thanks
