Microsoft.Web.Administration Namespace is wonderful! With couple of hours work I have managed to build a request monitor to watch who requesting what and how long it takes to serve. If you aren't bothered with the code below just download this requests.zip (38.69 kb) file and put it on a classic .net 4 application pool with and id that has administrator privileges. You won't be able to read system data if you use IUSR or apppool identity.
web.config

You can download zip file above if you want javascript enabled sorting of the requests table.
Have look at the end result below. Keepin mind that Country flags is not part of this sample but you can get the code for that from here

Since I started to develop with .Net 4 something was bugging me. I was unable to disable Request Validation like on 2. There is option on .Net 4 that you can set it .Net 2 model with
requestValidationMode="2.0"
So that you can enable/disable validation on page level. But, if you are using .Net 4 WebForms Routing sometimes you end up with errors like
A potentially dangerous Request.Path value was detected from the client
Although it is good thing to filter out dangerous requests in my case i need to have them present in the url.
There is a simple solution for it. You just need to set HttpRuntimeSection.RequestPathInvalidCharacters Property as you like. Default illegal chars are "<,>,*,%,&,:,\,?".
You can change them in your web.config. Here is my perefered settings
<httpRuntime requestValidationMode="2.0" requestPathInvalidCharacters="*,:" />
For more info read
