- All Implemented Interfaces:

public class GwtOpenLayersProxyServlet
- extends javax.servlet.http.HttpServlet
This is a transparent HTTP proxy written in Java that is similar to the proxy in
the OpenLayers examples, which is written in Python. These proxies are used
to circumvent browser restrictions on cross-domain requests with Javascript.
To use the proxy you need to 1) configure the proxy servlet in your web.xml
and 2) use OpenLayers.setProxyHost to set the url-path to the proxy. If the
proxy is configured to listen to the url-pattern '/gwtOpenLayersProxy/*' then
the proxy host should be set to 'gwtOpenLayersProxy?targetURL='.
Initial code for this proxy is based upon the
following code
