Hi Dom,

I think what is different here is who is doing what.

We were having problems getting Browser to do what they should, specifically the IE.
It was not issuing a HEAD request when you would expect it too.

While you are correct, with all things being done correctly, you would simply expect the behavior listed.
However, if a proxy is not configured the IE requests the full content everytime, resulting constantly in 200 response code.

As such the behavior listed below simply confirms that the browser acted correctly.

Does that answer your question?
