looks ok, though I haven't worked on this code.

Hi Ariana,

Can you please make this an opt-in/configurable option. Explorer isn't only used by DEA, and this change would be most unexpected in other environments. :)

Cheers

an opt-in/configurable option

Yes, I expect this would be good to have configurable by a deployment admin. Sharing some ideas, if helpful.

If URL converting regexs or functions were imported from settings.env.py we'd need to consider the security implications and do some careful vetting. I'm not sure of the effort or appetite to look at it from that perspective. A transparent in-code solution would be easier.

As a deployment patch perhaps? Perhaps settings.env.py could reference an as_external_url function that can be imported by explorer, else the "s3" default is used. The custom as_external_url function would need to be uploaded to the host running explorer. This may require an update to the explorer chart too.

Could we please update this to latest develop to avoid potential merge with rebase issues, especially if global settings are being changed. This will affect the main file where the timezone setting was recently added.
