encodeURL

public java.lang.String encodeURL(java.lang.String url)
                           throws java.lang.IllegalArgumentException

Encodes the specified URL by including the session ID in it, or, if encoding is not needed, returns the URL unchanged. The implementation of this method includes the logic to determine whether the session ID needs to be encoded in the URL. For example, if the browser supports cookies, or session tracking is turned off, URL encoding is unnecessary.

For robust session tracking, all URLs emitted by a servlet should be run through this method. Otherwise, URL rewriting cannot be used with browsers which do not support cookies.

Parameters:

url - the url to be encoded

Returns:

the encoded URL if encoding is needed, the unchanged URL otherwise

Throws:

java.lang.IllegalArgumentException - if the url is not valid or null

encodeURL

public java.lang.String encodeURL(PortletURL portletURL,
                                  java.lang.Boolean wantSecure,

                                  boolean relative)

Parameters:

portletURL - the portlet url

wantSecure -

wantAuthenticated -

relative -

Returns:

the url
