When content/article is created the content is accessible first on the http link and then later the httpS link. There is usually a delay of at least 5mns for anonymous to access it.
The cache settings have been modified for the content type to refresh cache on update and insert but it seems to affect the http links only not httpS. This is a problem as some time sensitive items don't get to the audience in a timely matter using httpS links.
How to make httpS links available as soon as it is published to anonymous?
