1. Download the proxy.cgi file from the OpenLayers web site:
http://trac.osgeo.org/openlayers/browser/trunk/openlayers/examples/proxy.cgi
Comment: This file is also included in the OpenLayers API download:
http://trac.osgeo.org/openlayers/wiki/HowToDownload
2. Modify the proxy.cgi file to include your domain in the allowedHosts list:
allowedHosts = ['www.yourdomain.com:8080']
Comment: Note that you have to include domain AND port here.
3. Copy the proxy.cgi file to the following folder:
$TOMCAT_PATH$/webapps/yourApp/WEB-INF/cgi/
4. Modify the file web.xml of your web app by adding the sections below. You find the file at
$TOMCAT_PATH$/webapps/yourApp/WEB-INF/web.xml
Comment: In case the web.xml file doesn’t exist for your webapp, just create it yourself or copy it from another webapp and modify it.
Comment: the “param-value” for the “executable” parameter has to contain the path to your Pyhton installation.
