Google Inc. about the cancellation of the change related to stricter restrictions on Cookie transmission between non-HTTPS sites. Starting from February, this change was gradually communicated to users. . It is noted that despite most websites adapting to this restriction, due to the SARS-CoV-2 coronavirus pandemic, Google decided to postpone the implementation of new restrictions that could potentially affect the stability of operations for sites providing essential services such as banking, online products, government services, and medical services.
The proposed restrictions prohibited the processing of third-party Cookies for non-HTTPS requests issued when accessing sites other than the current page's domain. Such Cookies are used to track user movements between sites in advertising network codes, social media widgets, and web analytics systems. It is important to note that the Cookie transmission is managed by the SameSite attribute specified in the Set-Cookie header, which by default was set to 'SameSite=Lax', limiting the sending of Cookies for cross-site sub-requests, such as image requests or loading content via iframe from another site.
