ServiceStack order of operations

The Implementation architecture diagram shows a visual cue of the order of operations that happens in ServiceStack. Where:

  1. EndointHostConfig.RawHttpHandlers are executed before anything else, i.e. returning any ASP.NET IHttpHandler by-passes ServiceStack completely.
  2. The IAppHost.PreRequestFilters gets executed before the Request DTO is deserialized
  3. Request Filter Attributes with Priority < 0 gets executed
  4. Then any Global Request Filters get executed
  5. Followed by Request Filter Attributes with Priority >= 0
  6. Action Request Filters (New API only)
  7. Then your Service is executed
  8. Action Response Filters (New API only)
  9. Followed by Response Filter Attributes with Priority < 0
  10. Then Global Response Filters
  11. Followed by Response Filter Attributes with Priority >= 0

Any time you close the Response in any of your filters, i.e. httpRes.Close() the processing of the response is short-circuited and no further processing is done on that request.
