WKWebView can't carry cookie for 302 redirect

Question

I set cookie in request header before I call loadRequest() function to load a page. I also use document.cookie() to set cookie by WKUserScript according to [WKWebView Cookie

Answer 1

Note sure, but probably the first response may contain "Set-Cookie" header. Hence, you have to use the provided cookie in the second request. May be it's missing.
