Understanding Isolation of HTML5 localStorage Object

Question:

In HTML5, does the localStorage object maintain isolation across different pages and domains? This question arises due to concerns regarding key naming conventions and potential conflicts.

Answer:

The HTML5 localStorage object exhibits isolation based on the domain and port. This means that the storage of data is segregated based on these parameters, similar to the rules governing the same-origin policy. To isolate localStorage data per page, you would need to employ a key naming convention based on the location or adopt alternative approaches.

It is essential to note that prefixing localStorage keys is not strictly mandatory. However, it is recommended to use a prefix if you anticipate potential conflicts. Furthermore, you are free to name your localStorage keys as desired within the constraints of your naming convention.
