css

We are experiencing an interesting issue with IIS 7.5 static caching and a css file.

When we use IE to hit the page in question everything works fine - 200 OK on css file.

When we refresh the page it works fine - 304 Not Modified on css file.

When I refresh again with control key it reloads fine - 200 OK on css file.

Now if I do a control key + refresh multiple times in a row really fast the css fails to load and in the developer tools network it says "Loading..." for the css file and it hangs never coming back.

Any ideas?
