dods.servlet.jake.DispatchServlet
dods.servlet.jake.ProxyServlet
- All Implemented Interfaces:
- java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
- public class ProxyServlet
- extends DispatchServlet
Proxy servlet. This servlet searches its parameter list for a server URL
which matches the first component of the path, and if it finds one,
acts as a proxy for DODS requests on the remote server. This can be used
by DODS applet clients to bypass the default applet security restrictions,
which only allow an applet to connect to the host from which they are
downloaded.
Note: to use this servlet, you'll need to add servlet parameters of the form:
manta=http://manta.jpl.nasa.gov/cgi-bin/nph-hdf
This will convert a URL of the form:
http://machine/servlets/proxy/manta/foo.hdf
to:
http://manta.jpl.nasa.gov/cgi-bin/nph-hdf/foo.hdf
