title: Is there any solution to hide Authorization from request headers or hide token
body: <p>I'm trying to secure my web site, i want to hide Authorization or just hide token.</p>
  
  <p>i'm using angular 7, and IIS server. </p>
  
  <p>this is when i use my token in Front-end side:</p>
  
  <pre><code>   var headerOptions = new Headers({
          'Content-Type': 'application/json',
          'Authorization': 'Bearer ' + this.token,
          'contrat_token': this.contrat_token
      }); 
  
      let options = new RequestOptions({
          search: params,
          headers: headerOptions
      });
  
      return this._http.get(url, options).pipe(map(resp =&gt; {
          if (resp.status === 401 || resp.status == 401 || resp.status.toString() == "401") {
              this.clearCookie();
          }
          else {
              let reponse = JSON.parse(resp.json());
  
              if (reponse == -1 || reponse == "-1") {
                  this.router.navigate(["/"]);
              }
          }
  
          return JSON.parse(resp.json())
      }
      ), catchError((error) =&gt; {
          if (error.status == 401 || error.status == "401") {
              this.clearCookie();
          }
          return of();
      })
      );
  </code></pre>

  <pre><code>     Authorization: Bearer THL8iBl4y4QTMh8sz8UluO3vDbtVib2Axp-_zYcPRGQVesnzDJVdFVq3GsYXeo4znSMbGqKNmLcGL_inNsMWAtc22
  </code></pre>
