title: How to delete orphaned objects from the persistent store during POST requests with RestKit?
body: <p>I am trying to use the delete orphaned objects feature of RestKit 0.20+ but it looks like it only supports GET request.</p>
  
  <p>I am using POST requests instead and I do not have access to the server configuration to switch GET support on. And as a side note, I probably couldn't use GET anyway as the objects posted are sometimes bigger than 1024 bytes.</p>
  
  <p>Is there any way to turn it on for POST requests as well?</p>
  
  <p>If not, is there any way to add some custom code to do a check on the returned response and eventually delete objects from Core Data before RestKit serializes them to the store?
  That way I could just add a custom check on a custom cache key and clear the data accordingly.</p>
