Google announced experimental HTTPS support in Blogger (Blogspot) last September. An announcement from the company today says that the tests went well, so the protocol is coming along like a prochoice for all the blogs of the users of the platform.
As early as September, the company had added a Blogger management setting that allowed users to enable HTTPS security links on their blogs.
This setting no longer exists as the feature applies by default to all blogs. In place of the removed setting there is a new option listed as “HTTPS redirect.”
This option, if enabled, will automatically redirect all blog visitors to HTTPS URL instead of HTTP links.
This redirection works automatically, and users who click on links that are posted on social networks or other pages will automatically be transferred to secure HTTPS connections without having to do anything.
In September, the first tests showed errors in the blogs they use subdomains, such as username.blogspot.com, and not on blogs that run on custom domains, such as userdomain.com.
The error was known as "mixed content" and according to Google some subdomains blogs are likely to encounter similar errors.
This has created a tool to help you identify mixed content errors, and fix your web pages.
