I'm in much the same boat. I've been using openLayer's python based proxy, but wouldn't mind seeing a more secured php based one, if you'd be willing to post. Of course, I'm currently limited to php4, so I may not be able to use it, but... still curious.
Also, phil?, what are you querying against? If Geoserver, it has tickets to introduce jsonp to wfs-getfeature at some point, but its not there as yet. Andrea set the version as 1.7.1 ( http://jira.codehaus.org/browse/GEOS-1411).<http://jira.codehaus.org/browse/GEOS-1411> Opening a ticket or asking about outputformat=jsonp for getCapabilities would probably be good thing. Full jsonp support for the wms/wfs would be very powerful. -josh On Tue, Sep 23, 2008 at 9:41 PM, Michael Geary <[EMAIL PROTECTED]> wrote: > > > I'm writing an OGC/WMS Viewer using jQuery.
