reverse proxy issue? Fails on 15.1.5 works on 15.0.17

[PDSBILL]

Have you read the document I posted above?

Yes,

What I posted before, was what the web.config looked like that works with 15.0.17 but fails with 15.1.9.
I was hoping it might help explain why one version works and the other does not.

We are going to setup the proxy this week exactly as shown in your example just changing the URL's and App Name.

Also there is a minor typo in your document. you are missing the ending single quote character at end of self.RewriteURL := '/MyApp;


 Similarly, in case of our ISAPI application we have:

Code:

procedure TIWServerController.IWServerControllerBaseConfig(Sender: TObject);
begin
  Self.RewriteURL := '/MyApp;  // this must match the URL Rewrite rule
end;

I just modified my app to go to the next page using the OnClick vs the OnAsyncClick event and it works.
I do not know if this helps, but wanted to let you know.
