Here's some context for why I brought this up:

If the user accesses pod A through the apiserver proxy, and pod A wants to generate a page that links to pods B and C via the proxy, then pod A needs a way to know what address the user originally used to get to the apiserver.

Either that, or the apiserver proxy needs some way to know when a cross-host link generated by pod A is actually a link to another pod, and should be rewritten to go through the proxy. For example, if there were such a thing as per-pod DNS entries, then pod A could link to http://pod-name.pods.skydns.local/status and apiserver proxy could rewrite it to https://apiserver/api/v1beta1/proxy/pods/pod-name/status.

@nikhiljindal Can you take a look at this? Feel free to reassign it back to me.

Ahh, I didn't realize that Eric already has a PR for this, and the original code was written by me anyway. Reassign it back myself.
