Hey Phil,
I'd just request the file with a GET request, e.g.
http://localhost:8080/geoserver/wfs?service=WFS&request=GetFeature&version=1.1.0&typeName=topp:states&outputFormat=shape-zip
If you have to include filters that make the URL too long for a GET
request, you can dynamically create a HTML form and add the parameters
as hidden fields, e.g.
var form = document.createElement("form");
form.method = "POST";
form.action = "http://localhost:8080/geoserver/wfs";;
var input = document.createElement("input");
input.type = "hidden";
input.name = "request";
input.value = "GetFeature";
form.appendChild(input);
// repeat the above 5 lines for all parameters
document.body.appendChild(form);
form.submit();
This would result in submitting the following form:
<form method="POST" action="http://localhost:8080/geoserver/wfs";>
<input type="hidden" name="request" value="GetFeature"></input>
</form>
The above is untested, but the same is done in
OpenLayers.Tile.Image.IFrame, and I guess you get the picture.
Regards,
Andreas.
