HTTP sources (w/o VSICURL) fail

[mojodna]

This previously worked (where it would download the entire file vs. reading it block by block using VSI):

gdalinfo http://oam-dynamic-tiler-tmp.s3.amazonaws.com/sources/57fc935b84ae75bb00ec751b/index.vrt

However, in 2.1.1, it now fails:

$ gdalinfo http://oam-dynamic-tiler-tmp.s3.amazonaws.com/sources/57fc935b84ae75bb00ec751b/index.vrt
ERROR 1: An error occurred while creating a virtual connection to the DAP server:
Error while reading the URL: http://oam-dynamic-tiler-tmp.s3.amazonaws.com/sources/57fc935b84ae75bb00ec751b/index.vrt.ver.
The OPeNDAP server returned the following message:

        Often this means that the OPeNDAP server is missing or needs attention;
        Please contact the server administrator.

This is not version dependant, but rather if you have the DODS driver enabled. The DODS driver recognizes ​http:// strings as his. If you do GDAL_SKIP=DODS this should work

Aha! That was totally it. Thanks!
