Hello! I want to query local and remote feature information for WMS layers. I have a server on which stays a javascript/html map viewer with ExtJs and Openlayers, in the back runs a Geoserver 2.0.2. I installed the Geoserver Proxy Extension on my server to access also a remote server. On my server the html file is in the C:\Program Files\GeoServer 2.0.2\webapps\geoserver folder. I added two hosts (without port) to the permitted hostnames: the server localhost (but with the server address not 'localhost') and a remote server host (IP address) where another geoserver is running. When I try to access the html map viewer from another PC the getfeatureinfo request requires an authentification (the geoserver username and password). And only the first host on that I try to ask the feature information gives me an reply, the other host is not responding. But when I begin with the other host it's the other way round. Like random. When I insert the url in the browser address box (http://serverhost:8080/geoserver/rest/proxy?url=getfeatureinfo-request) I have to authentificate! On the server the getfeatureinfo request works without authentification, but that's not intended. Without proxyhost I get only the feature information for the layers that are local. I tried also OpenLayers.ProxyHost = "/cgi-bin/proxy.cgi?url="; But the response is only the plain text of the cgi file. Who's familiar with proxy and local/remote WMS layers? Thank you for suggestions Lucia

I am trying to use the example at http://openlayers.org/dev/examples/wfs-spatial-filter.html with my own WFS (UMN Mapserver) but I am having a hard time getting some problems fixed. When I load my test page for the first time OpenLayers sends the following request: <wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; service="WFS" version="1.0.0" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd";> <wfs:Query typeName="omega"> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc";> <ogc:BBOX> <ogc:PropertyName>the_geom</ogc:PropertyName> <gml:Box xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326"> <gml:coordinates decimal="." cs="," ts=" ">135.45,-47.425 157.95,-36.175</gml:coordinates> </gml:Box> </ogc:BBOX> </ogc:Filter> </wfs:Query> </wfs:GetFeature> I get a valid response and the data is properly displayed on the map. When, however, I try to use a spatial filter in the request, like this... <wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; service="WFS" version="1.0.0" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd";> <wfs:Query xmlns:ms="http://mapserver.gis.umn.edu/mapserver"; typeName="ms:omega"> <ogc:Filter xmlns:ogc="http://www.opengis.net/ogc";> <ogc:And> <ogc:Intersects> <ogc:PropertyName>the_geom</ogc:PropertyName> <gml:Polygon xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326"> <gml:outerBoundaryIs> <gml:LinearRing> <gml:coordinates decimal="." cs="," ts=" ">142.28349609375,-40.5255859375 142.2615234375,-43.49189453125 148.1501953125,-44.15107421875 149.40263671875,-39.44892578125 142.28349609375,-40.5255859375</gml:coordinates> </gml:LinearRing> </gml:outerBoundaryIs> </gml:Polygon> </ogc:Intersects> <ogc:BBOX> <ogc:PropertyName>the_geom</ogc:PropertyName> <gml:Box xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326"> <gml:coordinates decimal="." cs="," ts=" ">135.45,-47.425 157.95,-36.175</gml:coordinates> </gml:Box> </ogc:BBOX> </ogc:And> </ogc:Filter> </wfs:Query> </wfs:GetFeature> ... one of the two following things will happen: 1. I get a "Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request." The logfile says "Premature end of script headers: mapserv.exe, referer: http://localhost/";. 2. This is the response: <wfs:FeatureCollection xmlns:wfs="http://www.opengis.net/wfs"; xmlns:ms="http://mapserver.gis.umn.edu/mapserver"; xmlns:gml="http://www.opengis.net/gml"; xmlns:ogc="http://www.opengis.net/ogc"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd http://mapserver.gis.umn.edu/mapserver http://localhost/cgi-bin/mapserv.exe?map=E:/ms4w/Apache/htdocs/mapservertest/wfs.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=ms:omega&OUTPUTFORMAT=XMLSCHEMA";> <gml:boundedBy> <gml:Box srsName="EPSG:4326"> <gml:coordinates>-1.000000,-1.000000 -1.000000,-1.000000</gml:coordinates> </gml:Box> </gml:boundedBy> </wfs:FeatureCollection> Which one of the two possibilities happens appears to be random. I am using the proxy.cgi and when I run http://localhost/cgi-bin/proxy.cgi I see the OpenLayers website. Any ideas? This is how my wfs-spatial-filter.js looks like: OpenLayers.ProxyHost= "/cgi-bin/proxy.cgi?url="; ..... var layer = new OpenLayers.Layer.Vector("WFS", { strategies: [new OpenLayers.Strategy.BBOX()], protocol: new OpenLayers.Protocol.WFS({ url: "http://localhost/cgi-bin/mapserv.exe?map=E:/ms4w/Apache/htdocs/mapservertest/wfs.map";, featureType: "omega", featurePrefix: "ms" }) }); .... The rest of the file looks exactly like in the example at http://openlayers.org/dev/examples/wfs-spatial-filter.js Thanks for your help!
