Are you really intending to overload POST (by sending your data as a query string)? Try this: OpenLayers.Request.POST({ url: printURL, data: OpenLayers.Util.getParameterString({ width: size.w, height: size.h, tiles: tiles_json }), callback: function(request) { alert(request.status); alert(request.responseText); } }) A few things to note: 1) The OpenLayers.Request functions are straight-up functions, not object constructors. So, no need to use the "new" keyword. Read http://trac.openlayers.org/wiki/Request for examples of their use. 2) The "params" option to a GET request gives you URI component encoding of your params property/value pairs in a GET query string. This is not for use in other request methods. 3) The OpenLayers.Util.getParameterString function takes an object and serializes property/value pairs using form-encoding (with the exception of array values). This is typically what you should be sending as the data in a POST request. I have no idea if your service properly reads form encoded data from POST - but it should. 4) If the responseText is not html (like maybe pdf, png, or some other image type), you should not be stuffing it into a new window. When IE supports the data: scheme, this could work. I should probably read the wiki page that you reference, you might not be doing this at all. Anyway, if the above works, then you can do what you want to with the response. Tim > > All works as expected in Firefox.
