Class ProxyWriter

java.lang.Object
  org.jasig.portal.serialize.ProxyWriter

public class ProxyWriter
extends Object

Appends PROXY_REWRITE_PREFIX string in front of all the references to images that are on a remote location that start with http://. This allows the browser to load the resources without triggering a warning about mixed content. For example instead of http://www.abc.com/image.gif the URI will be rewritten to https://[portaladdress]/PROXY_REWRITE_PREFIX/www.abc.com/image.gif This class also does the proxy rewrite in the following exceptional situations: 1. If the return code pointing to the image is 3XX (the image reference, references is a mapping to a different location) In this case the final destination address in which the image or the resource is located is e and then the rewrite points to this location. 2. If the content of a channel is an include javascript file the file is rewritten to a location on a local virtual host and at the same time the image or other resources references are rewritten.
