Re: [oslc-ccm] Caching versioned resource when passing config context in header
Perhaps one solution to this is for the
response to include a Vary=Configuration-Context header so that different
configuration contexts do not use a previously cached response. If so,
this might be worth mentioning in the Config Mgmt spec.

Best regards,

David.

   [oslc-ccm] Caching
versioned resource when passing config context in header

Nick et al., I want to make sure I understand
this...

https://tools.oasis-open.org/version-control/browse/wsvn/oslc-ccm/trunk/specs/config-mgt/config-resources.html#configcontext

 

If the server accepts a configuration context
in the header of the request, does that mean you've broken caching? Two
different requests may ask for the same resource, each with a different
header context, yielding a different resource.

 

Also, does the spec provide a method for
the client to discover which approach the service supports?

 

Thanks,
