I've just noticed that the slippy map within the wmflabs GeoHack page
does not work when accessed via HTTPS, and thought I should mention it here.
For example, compare:
http://tools.wmflabs.org/geohack/geohack.php?pagename=Foo¶ms=10_N_1…
with
https://tools.wmflabs.org/geohack/geohack.php?pagename=Foo¶ms=10_N_…
Could this be a mixed-content issue involving the script that drives the
slippy map not using protocol-relative URLs, or the slippy map tile
provider not responding to HTTPS?
