Question and requirements

Is it possible to HTTPRedirect from a Cloud CDF via e.g. Button action?

• I need an interactive cloud cdf around it.

• The action would not only redirect but evaluate arbitrary code prior to that.

• If it matters the target page does not need to be any page but an arbitrary CloudObject should do.

• No, I don't want to hide old stuff and show new to the user, I really need to redirect.

• No, open in new tab does not count.

So it would work analogously to this form's submit button:

CloudDeploy[
    FormFunction[{"go on and submit"}
      , Module[{link}
          , link = CloudPut[RandomReal[], Permissions -> "Public"]
          ; HTTPRedirect[link]
        ] &
    ]
  , Permissions -> "Public"
]

Problems

Wasn't able to achieve that, here's why:

• Form/ApiFunctions where HTTPRedirect works well can't have interative CDFs embedded inside:

   CloudDeploy[
       FormFunction[
           { "this is ok"
           , ExportForm["this is not ok", "CloudCDFElement"]
           }
         , foo
       ]
     , Permissions -> "Public"
   ]

• and I can't trigger HTTPRedirect from cloud CDF, nothing happens:

      CloudDeploy[
        ExportForm[
          Button["Submit", Print[1]; HTTPRedirect["http://www.wolfram.com"]], 
          "CloudCDFElement"
        ], Permissions -> "Public"
       ]
