From the Struts User Mailing List, I spotted a good explanation of how IE handles PDFs. It's quite messed up, so I thought I'd post it for your amusement.
More info on this "feature" is on Microsoft's site.
The JHipster Mini-Book is a guide to getting started with hip technologies today: Angular, Bootstrap, and Spring Boot. All of these frameworks are wrapped up in an easy-to-use project called JHipster.
This book shows you how to build an app with JHipster, and guides you through the plethora of tools, techniques and options you can use. Furthermore, it explains the UI and API building blocks so you understand the underpinnings of your great application.
