Hi Greg,
How did you change the THREDDS URL? Are you proxying it through apache?
Try changing the value of the "base" attribute in all the service
element to "/psd/thredds/*/" where "*" is one of "dodsC", "wcs", "wms",
etc. The values of "base" must be URLs that are relative to the server.
As long as all the proxy settings are correct, everything else should be
fine. By correct I mean such that the Java Servlet API returns the
proper values for context path ("/pds/thredds") and servlet paths
("/dodsC", "/wms", etc).
Let us know if you have any problems with that.
