This document summarizes a presentation about best practices in mobile web applications. It discusses: 1. Using cookies or HTML5 client-side storage for application data to avoid performance impacts of exchanging cookie data with the server on every request. 2. Ensuring security by only executing trusted JavaScript and safely parsing JSON data. 3. Informing users and giving them control over automatic network access and personal information use. 4. Conservative resource use through compression, minimizing requests, and inline scripts/stylesheets.
