CSRF is an attack which forces an end user to execute unwanted actions on a web application in which he/she is currently authenticated. With a little help of social engineering (like sending a link via email/chat), an attacker may trick the users of a web application into executing actions of the attacker’s choosing. A successful CSRF exploit can compromise end user data and operation in case of normal user. If the targeted end user is the administrator account, this can compromise the entire web application.

.Net .Net 4.0 ASP.Net Javascript

ASP.NET 4.5 includes a new feature to minify and bundle CSS and JavaScript within your web application. Static content like javascript and css files contains lot of white spaces and comments. Bundling and minification improves load time by reducing the number of requests to the server and reducing the size of requested assets (such as CSS and JavaScript.) In the past, the recommended technique was enabling compression either using programmatically (I have a post on enabling compression in using Http Module.), or you can configure it in IIS. But it was difficult configure and has got some performance issues.
