I found a pretty weird situation. The makerequest was failed when rendered by my shindig server.
However, it was rendered successfully by google server (http:// ig.gmodules.com), i.e., it can fetch the correct XML content. So is it the shindig server's bug? -- You received this message because you are subscribed to the Google Groups "OpenSocial Application Development" group.
