Web Development Helper
Web Development Helper plugs into Internet Explorer and provides tools for Ajax and Web development.
Web Development Helper is a free browser extension for Internet Explorer that provides a set of tools and utilities for the Web developer, esp. Ajax and ASP.NET developers. The tool provides features such as a DOM inspector, an HTTP tracing tool, and script diagnostics and immediate window.
Web Development Helper works against IE6+, and requires the .NET Framework 2.0 or greater to be installed on the machine.
Once installed, the tool can be activated using the Tools | Web Development Helper command. You can also customize your browser's toolbar to add a button for this command to facilitate frequest use. Clicking on the menu command or browser button brings up the tool's console window and set of commands.
Page Features:
• DOM inspector allows viewing all elements, selected elements, or elements matching an ID or CSS class, their attributes and styles.
• Capturing a screen shot of the current page.
• Viewing page information such as metadata, tags, and linked resources.
Networking Features:
• Logging HTTP (and HTTPS) requests initiated by the browser or Ajax scripts
