Delete Images on DNCA Side
When the DNCA is configured to be in BusinessIT mode, some image content types can be captured and passed to the Windows™ pipeline.In the pipeline, they were typically dropped by using the DelImages session agent.
- For more information about BusinessIT mode, see Capture Mode.
- For more information about the DelImages feature for the Windows™ pipeline, see "Data Drop Session Agent" in the Unica Discover Configuration Manual.
The DNCA now provides the DelImages functionality in the DNCA pipeline. When DelImages is enabled in the DNCA, the volume of data that is captured, processed, and transferred to the Windows™ server is reduced.
If a hit meets the following criteria, then the hit is identified as an image hit and is dropped:

- The following criteria is met:
- DNCA
CaptureType=3
and (StatusCode = 200
orStatusCode = 304
)- The previous criterion determines if the DNCA is in BusinessIT mode (CaptureType=3) and an image request is returned with an "okay" status or a Not Modified status (StatusCode =304).
- DNCA
If the previous criteria are met, then the image hit is dropped.
- When this feature is enabled, if
CaptureType=1
and the response content type is listed in the Include Extension list, then both the request and the response are captured.
