[Engine-devel] [Spice-devel] SPICE Foreign Menu Using REST

[Einav Cohen]

Hi Tomas,

Note that in the web-admin, we already have code that generates REST API session-ID;
this code is being utilized in the ui-plugins infrastructure to allow the different 
ui-plugins to communicate with the rest api.
[one related file is this context is RestApiSessionManager.java in the web-admin, not 
sure if there are others]

maybe the RestApiSessionManager(?) can somehow be utilized for the SPICE purpose as well 
(I guess that it will require a couple of code-changes though, and maybe worth moving it 
to gwt-common, to allow its utilization from the user portal as well?) - @Vojtech would 
probably know best to advise on this.

* Note: Today:
(a) a *single* REST API session-ID is generated and used across all ui-plugins in the system 
(upon user login to the web-admin).

(b) this REST-API session-ID is generated based on the *same credentials* with which the user 
logged into the web-admin.

both (a) and (b) will change once [1] will be addressed. 
Only for the SPICE case in particular - I think that (b) should remain. so maybe worth allowing 
both same-credentials-login and different-credentials-login in the REST-API-Session-ID-generation 
code in the GUI.

Thanks,
Einav

some of the planned changes (from the BZ description):
"""
...
- each UI plugin will have its own dedicated REST API session, unrelated to GUI (admin) 
user credentials
