URLRequest header permanent

I have webView in which I load some url. I need to set custom header for that URLRequest. For the first request it works as expected, header is received on server side and content is displayed accordingly. However if I open another link from displayed page, headers are lost and request is sent without header.

My lucky guess is that, header is added only for the first time and I have to add it every time when request to load url is sent. However I couldn't find method where can I do so.

Currently I'm setting header in viewDidLoad

override func viewDidLoad() {
    super.viewDidLoad()


    myWebView.delegate = self

    let url = URL(string: "https://mywebsite.com");
    var requestobj = URLRequest(url: url!);
    requestobj.addValue("my_request_id", forHTTPHeaderField: "X-Requested-With");

    myWebView.loadRequest(requestobj);

}

Am I missing something or should I add header in different place for every request?

Ok, thanks to iphonic, to pointing at shouldStartLoadWith. I could use that to understand is request new or old one and solve my problem by doing so:

func webView(_ webView: UIWebView,
                      shouldStartLoadWith request: URLRequest,
                      navigationType: UIWebViewNavigationType) -> Bool{


   if(navigationType == UIWebViewNavigationType.linkClicked) 
   {

        var req = request; 

        req.addValue("my_request_id", forHTTPHeaderField: "X-Requested-With"); 


        self.myWebView.loadRequest(req); 
            return false; 

    }
    else {
        return true; 
    }



}

So here I check, if navigation type is clickedLink, then I don't load current request, instead I copy it, reapply custom header and load it into myWebView. If navigationType isn't linkClicked, I proceed request without changes.

Yes, you should add custom headers each time when you create request.
