This has been stagnant for too long (incidentally, it was brought up at
yesterday's Snowglobe meeting.)
I think the way forward is standardizing this in a way that allows opensim to
implement it, not going back to UDP, region-local map tiles.
SNOW-77 has a patch attached that handles using a capability to find the base
url for the map tiles, but still sticks to assumptions about the url
I added a comment there last December, and will repeat it here, that I think
the grid should not just tell the viewer about the base url, but send a
template to prevent depending on a rigid url structure. This looks like
something RUSS can be used for, but that has a dire warning about security
implications of using an untrusted format string:
I don't know if this is a problem here (is it?), but I think we should find
*some* way to prevent hard-coding the url structure in the viewer.
