502 Bad Gateway

Question

I am trying to access the featureInfo in my application and I keep getting 502 Bad Gateway Network error. In teh console log under the response tab I am getting this error,

This proxy does not allow you to access that location (castle.iplantcollaborative.org:8080).

The GET param is,

http://castle.iplantcollaborative.org:8080/geoserver/wms/?LAYERS=opengeo%3APimaPine,opengeo%3ABIEN_Species_Richness_Margalef,opengeo%3ABIEN_Species_Richness,opengeo%3ABIEN_Species_Richness_Margalef_Interpolated&QUERY_LAYERS=opengeo%3APimaPine,opengeo%3ABIEN_Species_Richness_Margalef,opengeo%3ABIEN_Species_Richness,opengeo%3ABIEN_Species_Richness_Margalef_Interpolated&STYLES=,,,&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&BBOX=-18295967.087793%2C-10684061.894102%2C18295967.087793%2C10684062.234102&FEATURE_COUNT=10&HEIGHT=546&WIDTH=935&FORMAT=image%2Fpng&INFO_FORMAT=application%2Fvnd.ogc.gml&SRS=EPSG%3A900913&X=174&Y=140

My /usr/lib/cgi-bin/proxy.cgi has the domain's url added to it's allowed hosts. The apache error.log file was giving this error,

Permission denied: exec of '/usr/lib/cgi-bin/proxy.cgi' failed

But when I changed the chmod for the proxy.cgi file to root:root it is not giving that error but it continues to give 502 Bad Gateway. I know I need to make some changes somewhere in the user permissions but not sure where?

Any idea what I should correct?

Answer 1

solved the problem using proxy.php.

I got the file from the last Mapbuilder app, and its just copy the proxy.php file in my /var/www/ directory. In openlayers edit/add the line

OpenLayers.ProxyHost = "/proxy.php?url="

response to comment: To setup the proxy see Geoserver Documentation. http://geoserver.org/display/GEOS/GeoServer+Proxy+Extension

OH MY GOODNESS

I had to simply clear the browser history. This is so dumb :P

Just make sure you have the ip address or the domain name in the /usr/lib/cgi-bin/proxy.cgi is added to the allowed hosts.
