[OmniFaces utilities 2.0] Get the value of the HTTP request cookie associated with the given name

---

[OmniFaces utilities] The getRequestCookie() method returns the value of the HTTP request cookie associated with the given name. The value is implicitly URL-decoded with a charset of UTF-8.

---

Method:

See also: Utils#decodeURL()

Usage:

·         inside a servlet filter or even a plain vanilla servlet (basically, when FacesContext is not available):

import org.omnifaces.util.Servlets;

...

@WebServlet("/MyServlet")

public class MyServlet extends HttpServlet {

 protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

  // e.g. foo

  String foocookie = Servlets.getRequestCookie(request, "foocookie");

 }

 ...

}

·         in JSF, when FacesContext is available use, Faces#getRequestCookie(), or more clumsy (not recommended):

import org.omnifaces.util.Servlets;

...

// or simply use, Faces#getRequest()

Faces Context context = FacesContext.getCurrentInstance();

ExternalContext externalContext = context.getExternalContext();

HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();

// e.g. 5i2ngVpYIC3p4h-q_tROXRW-.leonard-pc

String jsessionidcookie = Servlets.getRequestCookie(request, "JSESSIONID");
