Open Source Diagnostics for .NET Applications

Glimpse allows you to debug your Web Service right in the browser. Glimpse allows you to "Glimpse" into what’s going on in your web server. In other words what Firebug is to debugging your client side code, Glimpse is to debugging your server within the client.
Fundamentally Glimpse is made up of 3 different parts, all of which are extensible and customizable for any platform:
- Glimpse Server Module
- Glimpse Client Side Viewer
- Glimpse Protocol
On the Server:
- Server collects all server side information that will aid in debugging (i.e. application settings, routes, session variables, trace data, etc)
- It does this by running through a pipeline of server side data providers that can be dynamically controlled and added to under plugin architecture
- Before the response is send, the server formats this data in accordance with the Glimpse Protocol and serializes it as JSON
- Depending on whether it is a Ajax request or not, the server embeds the JSON in the HTTP Header or in the content of the page
On the Client:
- Depending on whether it is a Ajax request or not, the picks up the JSON data and to the data set by executing a pipeline of client side data providers that can be dynamically controlled and added to under plugin architecture
- The client side module then dynamically renders a client side UI (similar to Firebug Lite) that lets you view this data
Glimpse can be turned on or off by a series of different mechanistic, but at its core if the Glimpse cookie is present the server will provide the "debug" data – as a security measure, the request for debug data is "authenticated". Via the plugin model, this authentication check can have any logic that is required by the site to ensure that unauthorized users don’t have access to sensitive debug data.
