[OpenLayers-Users] OpenLayers.Request POST and IE 6/7 issues

Wed Oct 29 15:06:35 EDT 2008

Ah, the key is at the bottom (content type):

OpenLayers.Request.POST({
     url: printURL,
     data: OpenLayers.Util.getParameterString(
         {width:size.w, height:size.h}
     ),
     headers: {
         "Content-Type": "application/x-www-form-urlencoded"
     },
     callback: function(request) {
         alert(request.responseText);
     }
});
