Logstalgia (also known as ApachePong) is a very powerful and handy app. It is a website access log visualization tool. It is an extremely useful tool to give you look at your web server traffic. I often use this kind of software to justify and convince my clients and/or boss that we need more servers to handle traffic. It streams Apache / Lighttpd / Nginx web-server access logs as a pong-like battle between the web server and a never ending torrent of requests.

The HTTP 2xx class of status codes indicates the action requested by the client was received, and processed successfully. HTTP/1.1 200 OK is the standard response for successful HTTP requests. When you type www.cyberciti.biz in the browser you will get this status code. The HTTP/1.1 206 status code allows the client to grab only part of the resource by sending a range header.

- Understanding http headers and protocol.
- Troubleshooting network problems.
- Troubleshooting large download problems.
- Troubleshooting CDN and origin HTTP server problems.

Mozilla Firefox version 11.x+ has support for 3D view. It is a WebGL based website visualization tool that highlights page structure. You can see relationship between your code and the page output by stacking elements as they are nested in the DOM and lets you see elements that are hidden or off the page. You can zoom in and out, rotate and pan the view to see the page from any angle that is helpful to you. In this blog post I will explain how to enable 3D view on X11. Please note that the 3D view is not for your daily browsing needs. It is useful for finding out bugs such as nesting issues or even XSS vulnerabilities. Personally, I use 3D view as a tool to understand divs, spans, and other elements on the page.
