A repro repo for issues with my fork of Nancy.Embedded.

1. Clone this project
2. Build the solution (i think NuGet should restore stuff correctly for you)
3. Select the Demo.FileSystem project and run it
4. Browse to http://localhost:8080 and open devtools -> network
5. Click on the link a bunch of times and watch the image only get loaded once

Then try the other project:

1. Select the Demo.Embedded project
2. Run it
3. Browse to http://localhost:4444 and open devtools -> network
4. Click on the link a bunch of times and watch the image only get loaded once

When i do this i see this diff between the headers in Fiddler gist.

i'm using Chrome Version 33.0.1750.146 m on Windows. Maybe this doesn't happen in other browsers? The whole reason i'm doing this is because i'm seeing this crop up in a real-world application on iOS Mobile Safari as well and it's messing up images used in real-time updates i have going in SignalR.

i have many questions

1. How can i improve in my devtools skills to figure out what is actually happening?
2. What causes a the browser to download an image tag inserted via javascript?
3. What is happening and how can i fix this?
