DO proxy the WMS tiles, to prevent mixing secure/insecure content

[mattfullerton]

I would like to propose proxying WMS tiles, to prevent mixing secure/insecure content. Maybe in the long term it should be configurable?

This could put a big burden on ckan and the web server (specially combined with #16). I think that it could make sense as an optional configuration.

Check the note regarding config options at the end of this section if you want to go down that route:

You're right. I'll add it to the config instead.

This PR is 7 years old and according to this comment it is superseded by a config. It also has conflicts, it can probably be closed
