Servlets (OmniFaces 2.5 API)

java.lang.Object
- org.omnifaces.util.Servlets

```
public final class Servlets
extends Object
```
Collection of utility methods for the Servlet API in general. Most of them are internally used by Faces and FacesLocal, however they may also be useful in a "plain vanilla" servlet or servlet filter.
There are as of now also five special methods related to JSF without needing a FacesContext:
- The getFacesLifecycle(ServletContext) which returns the JSF lifecycle, allowing you a.o. to programmatically register JSF application's phase listeners.
- The isFacesAjaxRequest(HttpServletRequest) which is capable of checking if the current request is a JSF ajax request.
- The isFacesResourceRequest(HttpServletRequest) which is capable of checking if the current request is a JSF resource request.
- The facesRedirect(HttpServletRequest, HttpServletResponse, String, String...) which is capable of distinguishing JSF ajax requests from regular requests and altering the redirect logic on it, exactly like as ExternalContext.redirect(String) does. In other words, this method behaves exactly the same as Faces.redirect(String, String...).
- The isFacesDevelopment(ServletContext) which is capable of checking if the current JSF application configuration is set to development project stage.
Those methods can be used in for example a servlet filter.

  - getRequestHostname
```
public static String getRequestHostname(HttpServletRequest request)
```
    Returns the HTTP request hostname. This is the entire domain, without any scheme and slashes. Noted should be that this value is extracted from the request URL, not from ServletRequest.getServerName() as its outcome can be influenced by proxies.
    
    Parameters:
    
    request - The involved HTTP servlet request.
    
    Returns:
    
    The HTTP request hostname.
    
    Throws:
    
    IllegalArgumentException - When the URL is malformed. This is however unexpected as the request would otherwise not have hit the server at all.
    
    See Also:
    
    HttpServletRequest.getRequestURL()
  - getRequestDomainURL

```
    Add a cookie with given name, value and maxage to the HTTP response. The cookie value will implicitly be URL-encoded with UTF-8 so that any special characters can be stored. The cookie will implicitly be set in the domain and path of the current request URL. The cookie will implicitly be set to HttpOnly as JavaScript is not supposed to manipulate server-created cookies. The cookie will implicitly be set to secure when the current request is a HTTPS request.
    
    Parameters:
    
    request - The involved HTTP servlet request.
    
    response - The involved HTTP servlet response.
    
    name - The cookie name.
    
    value - The cookie value.
    
    maxAge - The maximum age of the cookie, in seconds. If this is 0, then the cookie will be removed. Note that the name and path must be exactly the same as it was when the cookie was created. If this is -1 then the cookie will become a session cookie and thus live as long as the established HTTP session.

```
public static Lifecycle getFacesLifecycle(ServletContext context)
```
    Returns The Lifecycle associated with current Faces application.
    
    Parameters:
    
    context - The involved servlet context.
    
    Returns:
    
    The Lifecycle associated with current Faces application.

  - isFacesAjaxRequest
```
public static boolean isFacesAjaxRequest(HttpServletRequest request)
```
    Returns true if the given HTTP servlet request is a JSF ajax request. This does exactly the same as Faces.isAjaxRequest(), but then without the need for a FacesContext. The major advantage is that you can perform the job inside a servlet filter, where the FacesContext is normally not available.
    
    Parameters:
    
    request - The involved HTTP servlet request.
    
    Returns:
    
    true if the given HTTP servlet request is a JSF ajax request.
    
    Since:
    
    2.0
  - isFacesResourceRequest
```
public static boolean isFacesResourceRequest(HttpServletRequest request)
```
    Returns true if the given HTTP servlet request is a JSF resource request. I.e. this request will trigger the JSF ResourceHandler for among others CSS/JS/image resources.
    
    Parameters:
    
    request - The involved HTTP servlet request.
    
    Returns:
    
    true if the given HTTP servlet request is a JSF resource request.
    
    Since:
    
    2.0
    
    See Also:
    
    ResourceHandler.RESOURCE_IDENTIFIER
  - isFacesDevelopment
```
public static boolean isFacesDevelopment(ServletContext context)
```
    Returns true if we're in JSF development stage. This will be the case when the javax.faces.PROJECT_STAGE context parameter in web.xml is set to Development.
    
    Parameters:
    
    context - The involved servlet context.
    
    Returns:
    
    true if we're in development stage, otherwise false.

  - facesRedirect
```
public static void facesRedirect(HttpServletRequest request,
                                 HttpServletResponse response,
                                 String url,
                                 String... paramValues)
                          throws IOException
```
    Sends a temporary (302) JSF redirect to the given URL, supporting JSF ajax requests. This does exactly the same as Faces.redirect(String, String...), but without the need for a FacesContext. The major advantage is that you can perform the job inside a servlet filter or even a plain vanilla servlet, where the FacesContext is normally not available. This method also recognizes JSF ajax requests which requires a special XML response in order to successfully perform the redirect.
    If the given URL does not start with http://, https:// or /, then the request context path will be prepended, otherwise it will be the unmodified redirect URL. So, when redirecting to another page in the same web application, always specify the full path from the context root on (which in turn does not need to start with /).
```
 Servlets.facesRedirect(request, response, "some.xhtml");
 
```
    You can use String.format(String, Object...) placeholder %s in the redirect URL to represent placeholders for any request parameter values which needs to be URL-encoded. Here's a concrete example:
```
 Servlets.facesRedirect(request, response, "some.xhtml?foo=%s&bar=%s", foo, bar);
 
```
    Parameters:
    
    request - The involved HTTP servlet request.
    
    response - The involved HTTP servlet response.
    
    url - The URL to redirect the current response to.
    
    paramValues - The request parameter values which you'd like to put URL-encoded in the given URL.
    
    Throws:
    
    IOException - Whenever something fails at I/O level. The caller should preferably not catch it, but just redeclare it in the action method. The servletcontainer will handle it.
