Fiddler Web Debugging Proxy

Here's a useful tool for debugging web apps specifically running in IE versions 8 and below. This is not just limited to applications running on the browser though, it can listen to any application utilizing HTTP / HTTPS. You do not need to configure your proxy settings to redirect traffic, it just works on the fly.


IE 9 has Developer Tools in it, more info [here] just like FireBug for Firefox and Chrome Developer Tools.


It does not mean that we can not use it though. I would still recommend it for debugging HTTP / HTTPS communication to avoid looking at 3 different tools.

Moving on

So I bought my self a 2.5″ hard drive enclosure for about 750 bucks. I wish I have my own tools for constructing a device as such. Instead of going for a 2GB USB flash drive, I chose to salvage the 30GB hard drive of an incapacitated laptop. Cool isn’t it? Though relatively slower than a typical USB flash drive, the storage capacity outweighs it. [To God] Thanks for being there always.
