Redirect a request to the specified URL, and cause the responseComplete() method to be called on the FacesContext instance for the current request.

The implementation must determine if the request is an Ajax request by obtaining a PartialViewContext instance from the FacesContext and calling PartialViewContext.isAjaxRequest().

Jakarta Servlet: For non Ajax requests, this must be accomplished by calling the jakarta.servlet.http.HttpServletResponse method sendRedirect().

For Ajax requests, the implementation must:

• Get a PartialResponseWriter instance from the FacesContext.
• Call ExternalContext.setResponseContentType(java.lang.String) with text/xml
• Call ExternalContext.setResponseCharacterEncoding(java.lang.String) with UTF-8
• Call ExternalContext.addResponseHeader(java.lang.String, java.lang.String) with Cache-Control, no-cache
• Call PartialResponseWriter.startDocument()
• Call PartialResponseWriter.redirect(java.lang.String) with the url argument.
• Call PartialResponseWriter.endDocument()

Specified by:

redirect in class ExternalContext

Parameters:

url - Absolute URL to which the client should be redirected

Throws:

IOException - if an input/output error occurs

getRequestCharacterEncoding

public String getRequestCharacterEncoding()

Description copied from class: ExternalContext

Return the character encoding currently being used to interpret this request.

Jakarta Servlet: This must return the value returned by the jakarta.servlet.ServletRequest method getCharacterEncoding().

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

getRequestCharacterEncoding in class ExternalContext

Returns:

the character encoding currently being used.

setRequestCharacterEncoding

public void setRequestCharacterEncoding(String requestCharacterEncoding)
                                 throws UnsupportedEncodingException

Description copied from class: ExternalContext

Overrides the name of the character encoding used in the body of this request.

Calling this method after the request has been accessed will have no no effect, unless a Reader or Stream has been obtained from the request, in which case an IllegalStateException is thrown.

Jakarta Servlet: This must call through to the jakarta.servlet.ServletRequest method setCharacterEncoding().

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

setRequestCharacterEncoding in class ExternalContext

Parameters:

requestCharacterEncoding - the encoding name to be set.

Throws:

UnsupportedEncodingException - if this is not a valid encoding

getResponseCharacterEncoding

public String getResponseCharacterEncoding()

Description copied from class: ExternalContext

Returns the name of the character encoding (MIME charset) used for the body sent in this response.

Jakarta Servlet: This must return the value returned by the jakarta.servlet.ServletResponse method getCharacterEncoding().

Portlet: if this method is called during a lifecycle phase other than RENDER_RESPONSE, this must return null. If called during RENDER_RESPONSE, return the response encoding of the portlet response.

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

getResponseCharacterEncoding in class ExternalContext

Returns:

the name of the character encoding.

setResponseCharacterEncoding

public void setResponseCharacterEncoding(String responseCharacterEncoding)

Description copied from class: ExternalContext

Sets the character encoding (MIME charset) of the response being sent to the client, for example, to UTF-8.

Jakarta Servlet: This must call through to the jakarta.servlet.ServletResponse method setCharacterEncoding().

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

setResponseCharacterEncoding in class ExternalContext

Parameters:

responseCharacterEncoding - the character encoding to be sent by the current response.

setResponseHeader

public void setResponseHeader(String name,
 String value)

Description copied from class: ExternalContext

Set the response header with the given name and value.

Jakarta Servlet:This must be performed by calling the jakarta.servlet.http.HttpServletResponse setHeader method.

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

setResponseHeader in class ExternalContext

Parameters:

name - The name of the response header.

value - The value of the response header.

addResponseHeader

public void addResponseHeader(String name,
 String value)

Description copied from class: ExternalContext

Add the given name and value to the response header.

Jakarta Servlet:This must be performed by calling the jakarta.servlet.http.HttpServletResponse addHeader method.

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

addResponseHeader in class ExternalContext

Parameters:

name - The name of the response header.

value - The value of the response header.

encodePartialActionURL

public String encodePartialActionURL(String url)

Description copied from class: ExternalContext

Return the input URL, after performing any rewriting needed to ensure that it can be used in a partial page submission (ajax request) to correctly identify an addressable action in the current application.

See ExternalContext.encodeActionURL(java.lang.String) for the required specification of how to encode the ClientWindow.

Jakarta Servlet:Returns the same encoded URL as the ExternalContext.encodeActionURL(String url) method.

Portlet:Returns an encoded URL that, upon HTTP POST, will invoke the RESOURCE_PHASE of the portlet lifecycle.

Overrides:

encodePartialActionURL in class ExternalContext

Parameters:

url - The input URL to be encoded

Returns:

the encoded URL.

getRealPath

public String getRealPath(String path)

Description copied from class: ExternalContext

Returns a String containing the real path for a given virtual path.

It is valid to call this method during application startup or shutdown. If called during application startup or shutdown, this method calls through to the getRealPath() method on the same container context instance (ServletContext or PortletContext) as the one used when calling getRealPath() on the ExternalContext returned by the FacesContext during an actual request.

Jakarta Servlet: This must be the value returned by the jakarta.servlet.ServletContext method getRealPath().

The default implementation throws UnsupportedOperationException and is provided for the sole purpose of not breaking existing applications that extend this class.

Overrides:

getRealPath in class ExternalContext

Parameters:

path - The context of the requested initialization parameter

Returns:

the real path for the specified virtual path.
