In Openlayers, I have defined two sources and two layers, example :
const sourceWMSznieff1 = new ImageWMS({
  // serverType: "mapserver",
  projection: "EPSG:3857",
  params: {
    LAYERS: "znieff1_metropole",
    // _t: Date.now(),
  },
  url: "http://
.../mapserv.exe?MAP=C:/ms4w/Apache/site/mapfile/fond_iliad_natura.map&",
})

export const coucheWMSznieff1 = new ImageLayer({
  title: "znieff1",
  source: sourceWMSznieff1,
})

Only LAYERS and title are changing for the second source and layer Image.
In my browser, layers are different, i.e. they display their own datas,
only when I am loading just one.
But loaded together the two layers render the total features of the 2
shapefiles, so in a way the layers are duplicates.

Does it mean I have to create a mapfile for each shapefile ? (it seems
weird to me and I have many shapefile
