Hi, Your code snippet for google epsg:4326 and your wfs works. I have tried. Also the WFS request http://www.bsc-eoc.org/cgi-bin/bsc_ows.asp?typename=OWLS&SERVICE=WFS&VERSION =1.0.0&REQUEST=GetFeature&SRS=EPSG%3A4326&BBOX=-205.46875,-45.46875,5.46875, 165.46875 returns the features.
The problem is the right configuration of your proxy script or your proxy script have failures.

I tried that but so far with no success, and I wonder if it should work also with 4326, because I reprojected the whole Map to 4326?? var options = { maxExtent: new OpenLayers.Bounds(7.9189,52.2102,8.1716,52.3467), units: 'dd', projection: "EPSG:4326" }; ...and the WMS I have is also in 4326 and seems to lay correctly above the google-data. To come to the target step-by-step without eventually projection-mismatch I try the data from WFS-Example now: function init(){ OpenLayers.ProxyHost="/cgi-bin/proxy.cgi?url="; map = new OpenLayers.Map('map'); layer = new OpenLayers.Layer.WMS( "OpenLayers WMS", "http://labs.metacarta.com/wms/vmap0";, {layers: 'basic'} ); map.addLayer(layer); layer = new OpenLayers.Layer.WFS( "Owl Survey", "http://www.bsc-eoc.org/cgi-bin/bsc_ows.asp?";, {typename: "OWLS"}, { featureClass: OpenLayers.Feature.WFS}); map.addLayer(layer); map.addControl(new OpenLayers.Control.LayerSwitcher()); map.setCenter(new OpenLayers.LonLat(-100, 60), 3); } ...but also there on my development server the wfs is not visualized??? I set the proxy.cgi to the servers cgi-bin but without success (the proxy-cgi is executable and readable by the apache-group). Definetely cgi-scripts are parsed (I tested it with a little "Hello-World"-Python-Cgi. Bugtracker gives me after loading wfs.html in "red" a http://www.gastronomap.de/cgi-bin/proxy.cgi?url=http%3A%2F%2Fwww.bsc-eoc.org %2Fcgi-bin%2Fbsc_ows.asp% 3Ftypename%3DOWLS%26SERVICE%3DWFS%26VERSION%3D1.0.0%26REQUEST%3DGetFeature%2 6SRS%3DEPSG%253A4326%26BBOX% 3D-205.46875%2C-45.46875%2C5.46875%2C165.46875 ....if I open that in a browser nothing at all occurs, puh.... I wonder what else might create that error,hmmmmm, well maybe tomorrow I will find a solution.
