Class DefaultProxyUriManager

java.lang.Object
  org.apache.shindig.gadgets.uri.DefaultProxyUriManager

All Implemented Interfaces:

ProxyUriManager

public class DefaultProxyUriManager
extends Object
implements ProxyUriManager

Generates URIs for use by the Shindig proxy service. URIs are generated on the host specified in ContainerConfig at key "gadgets.uri.proxy.host". The remainder of the URL may reference either chained or query-style proxy syntax. The former is used when "gadgets.uri.proxy.path" has token "%chained_params%" in it. Chained: Returned URI contains query params in its path, with the proxied resource's URI appended verbatim to the end. This enables proxied SWFs to perform proxied, relative-URI resource loads. Example: http://www.example.com/gadgets/proxy/refresh=1&.../http://www.foo.com/img.gif Query param: All params are provided on the query string. Example: http://www.example.com/gadgets/proxy?refresh=1&url=http://www.foo.com/img.gif&... This implementation supports batched versioning as well. The old-style "fp" (fingerprint) parameter is not supported any longer; its functionality is assumed to be subsumed into the version param.

2.0.0
