[Engine-devel] Does RHEVM/Ovirt API violates the stateless requriement of REST?

[Jaroslav Henner]

Hi.

I think the fact that when updating (PUT), we may send only the updated 
xml elements violates following.

------8<------8<------8<------8<------
Figure 5-2: The client-server style
5.1.3 Stateless

We next add a constraint to the client-server interaction: communication 
must be stateless in nature, as in the client-stateless-server (CSS) 
style of Section 3.4.3 (Figure 5-3), such that each request from client 
to server must contain all of the information necessary to understand 
the request, and cannot take advantage of any stored context on the 
server. Session state is therefore kept entirely on the client.

Am I right? If so, this is quite huge violation. Much much bigger than 
some state of SESSION_ID/TOKEN. Would caches/proxies work well with 
current design?
