Video thumbnails – forwarding from DMA to DMA

Hi Dojo,

We’re trying to understand if it’s possible to forward video thumbnails over several DMAs. The setup is the following:

  1. A device is in the internal network. A client can view its thumbnails by connecting to DMA 1 which is also is in the internal network.
  2. DMA 2 is located in the external network, and is able to connect to DMA 1 with Replication, but is not able to connect to the device directly. It’s also possible to view the thumbnail from the external network by opening the VideoThumbnails page on DMA 1.
  3. The end user can connect to DMA 2 via Internet, but is not allowed to connect to DMA 1. With replication we’re able to share the data from the source device, but so far we haven’t been able to share the thumbnail. Theoretically, a hyperlink like https://<dma2><pointer to thumbnail on dma1><pointer to thumbnail on device> should allow that, but we haven’t found the way to get authorized at DMA 1, it responds with error 401 Not Authorized.

I hope this diagram helps explain what we’re trying to achieve:

So the question to Dojo is, is this way of replicating possible and how the authorization at DMA 1 can be resolved?

Thanks.

I think this is not possible out of the box in DataMiner, but there are alternatives. For example, on DMA2, you could make use of the URLRewrite module in IIS to configure a reverse proxy that forwards the request of the client directly to DMA1. This way you could make the thumbnail images accessible for the client.
