## Introduction Some security sensitive applications include compromise of their application server in the threat model. For example, end-to-end encryption is designed to protect the user against the developer's infrastructure...
## Introduction Client-side A/B testing refers to the method of performing experimentation related changes to a web application in the browser — sometimes without integrating code changes to the actual...
