Why are there so many cookie warnings now?

While they're fundamental to any website, cookies do raise some privacy concerns. That's the reason why some countries established cookie warning laws, calling for new requirements and safeguards to be put into place to ensure user privacy.

Is it necessary to have cookies?

Strictly necessary cookies are essential for websites to work because they help improve your experience on the site and make it easier for you to use. For example, cookies can be used to remember your language preferences and other settings that you've set in order to make your visit as efficient as possible.

Are Analytics cookies essential?

Consent is required because analytics cookies are not strictly necessary to provide the service that the user requests. For example, the user can access your online service whether analytics cookies are enabled or not.

What is a cookie length warning?

Currently if the cookie exceeds 4000 bytes it will fail to store in most modern browsers. This results in the user either repeatedly sending an older smaller session object, or having no session at all.
