msLocalStorageTest_* Cookie

What does the msLocalStorageTest_* cookie do?

This cookie is used to test if a user's browser supports storing data locally on their device using web storage. It's a test cookie that attempts to write and read data from the local storage, checking whether the operation was successful.

Why this cookie matters

This cookie is commonly used by google-analytics for preferences purposes – such as tracking usage behaviour, optimising experience, or enabling marketing functionality.

Because it's categorised as preferences, many jurisdictions require that users give explicit consent before it can be activated. If blocked or denied by the visitor, preference-related features (like remembering language or layout choices) may not function properly.
