As I understand, theoretically you need a method wiiPerformHTTPRedirection of NSURLSession delegate. But:
1) B4i sets own delegate and to expand it without source code is a problem.
2) As I understand, if server returns 200 instead of 307, wiiPerformHTTPRedirection does not work,
Why HttpUtils exactly ? For example, to control WKWebView is enough simple (navigationDelegate, decidePolicyForNavigationAction:...)
I use HttpUtils2 because I have created an alternative Multiplatform client to a webApp.
I need to read the server responses to populate the masks and respond to the server.
Sometimes the server responds with page 302 and redirects me. I need to know when it happens and manage it. At the moment httpUtils does it all by itself.
