[MapProxy] non-MIME supported format for WMS source

[Pestereva, Anna]

Hello all,

I am trying to use a WMS source that only works when requested in 'JPG'
format, not 'image/jpeg'. I am trying following in my configuration:

  lidar_wms:
    type: wms
    req:
      url: http://ortho.gis.iastate.edu/server.cgi?wmtver=1.0
      layers: lidar_hs
      transparent: true
    supported_srs: ['EPSG:26915']
    supported_formats: ['JPG']
    coverage:
      bbox: [-96.8, 39, -90, 45.1]
      bbox_srs: 'EPSG:4326'

globals:
  image:
    formats:
      JPG:
        format: image/jpeg


However I am still receiving error response from the server - "Unsupported
format image/jpg. Try JPG instead." So it looks like even when specifying
custom format xxx, Mapproxy sends request as image/xxx. But this source
will only accept exact 'JPG' requests.

What can I do to make it work?

Example of successful request:
http://ortho.gis.iastate.edu/server.cgi?wmtver=1.0&SERVICE=WMS&REQUEST=GetMap&VERSION=1.1.1&LAYERS=lidar_hs&FORMAT=JPG&HEIGHT=256&WIDTH=256&SRS=EPSG%3A26915&BBOX=524288,4587520,655360,4718592

Thank you!
