My issue is that i want to make redirection to action in another Controller with POST DATA not a GET
RedirectToAction("GenaraleExportPDF", "ExportController", new {
screendata = json, monTitre = monTitre, file = file, block1 = block1, block2 = block2, block3 = block3, block4 = block4
});
this example exaplaine the redirection but on GET Action.
