Subject Added new headers to API response
Date Fri, 07 Jan 2011 13:24:30 GMT
Hi,

This patch simply add ETag[1] support for all our string responses.
Suppose of this is to give client an option to check if response
was changed or not (like for checking instance status) without
parsing XML.

Another thing which this patch add is X-Runtime and X-Backend-Runtime
headers, where you can find timings or request and also timing
of 'backend' operation (mean how long takes to get response from backend)
This patch could be used for performance benchmarks...
