Hi Dojo,

A few questions came up while working on some optimizations in a cluster - I'd need to make sure that DataMiner end-points are never polled via a web-proxy, where a proxy must be configured for other purposes.

For simplicity, let's assume a scenario with 5 DMAs in the cluster,
with DMA01 and DMA02 being the two on which SAML access is configured and so a proxy must be added to reach my external authentication.

From proxy logs, I can see that the 2 "SAML" DMAs keep sending this kind of "GET"

e.g.
<Source-DMA01-IP> GET http://<DMA03-IP>/Endpoints.txt
<Source-DMA01-IP> GET http://<DMA04-IP>/Endpoints.txt
<Source-DMA01-IP> GET http://<DMA05-IP>/Endpoints.txt

<Source-DMA02-IP> GET http://<DMA03-IP>/Endpoints.txt
<Source-DMA02-IP> GET http://<DMA04-IP>/Endpoints.txt
<Source-DMA02-IP> GET http://<DMA05-IP>/Endpoints.txt

Cannot see the reverse request in this log, so DMA03, DMA04 and DMA05 are either not requesting the
endpoints or successfully bypassing the proxy (which is what I would like to achieve also for DMA01 and DM02).

How often are these "Endpoints" requests needed in a DMS?

Any way I can can cache these in cluster configurations on each DMA (xml files)?
And if not, is there any way of setting this GET at application layer to never use a proxy? 

In DMS.xml I can see that for DMA03, DMA04 and DMA05
some "lost contact" timestamps are reported:

Checked winhttp & Internet-Options:

DMS addresses seem to be correctly added to the bypass lists there - suspecting something at GPO layer may kick-in, hence why I'm wondering if there is any application settings I could leverage to force this kind of requests to not use a proxy - any steer will be helpful.

Versioning info at the bottom.

Thanks
