Class CookieSessionHandler
java.lang.Object
sunlabs.brazil.handler.CookieSessionHandler
- All Implemented Interfaces:
Handler
Handler for creating browser sessions using cookies.
This handler provides a single cookie-id that may be used by
other handlers.
The intent is to require only one cookie per server.
(See also
SessionFilter
, which
manages sessions with or without cookies).
The following server properties are used:
- prefix, suffix, glob, match
- Specify the URL that triggers this handler
(See
MatchString
).If
prefix
is specified, it is also used to instruct the client to limit the scope of the browser cookie. to that prefix. - cookie
- the name of the cookie to use (defaults to "cookie").
-
map
- If specified, the
ident
argument toSessionManager.getSession(Object, Object, Class)
to get the table of valid cookies, used to map the cookie value to a Session ID. By default, the Session ID stored in the request is the cookie value itself. -
exist
- If specified, this means that the Session ID corresponding to the
cookie value must already exist in the
SessionManager
. Normally, if the cookie was not present, a new cookie is automatically created. - persist
- If set, cookies persist across browser sessions
-
session
- The name of the request property that the Session ID will be stored in, to be passed to downstream handler. The default value is "SessionID". If the property already exists, and is not empty, no action will be taken.
gotCookie
is set to the cookie name. Otherwise it is left unset.- Version:

init
Description copied from interface:Handler
Initializes the handler.- Specified by:
init
in interfaceHandler
- Parameters:
server
- The HTTP server that created thisHandler
. TypicalHandler
s will useServer.props
to obtain run-time configuration information.propsPrefix
- The handlers name. The string thisHandler
may prepend to all of the keys that it uses to extract configuration information fromServer.props
. This is set (by theServer
andChainHandler
) to help avoid configuration parameter namespace collisions.- Returns:
true
if thisHandler
initialized successfully,false
otherwise. Iffalse
is returned, thisHandler
should not be used.
-
respond
Description copied from interface:Handler
Responds to an HTTP request.- Specified by:
respond
in interfaceHandler
- Parameters:
request
- TheRequest
object that represents the HTTP request.- Returns:
true
if the request was handled. A request was handled if a response was supplied to the client, typically by callingRequest.sendResponse()
orRequest.sendError
.- Throws:
IOException
- if there was an I/O error while sending the response to the client. Typically, in that case, theServer
will (try to) send an error message to the client and then close the client's connection.The
IOException
should not be used to silently ignore problems such as being unable to access some server-side resource (for example getting aFileNotFoundException
due to not being able to open a file). In that case, theHandler
's duty is to turn thatIOException
into a HTTP response indicating, in this case, that a file could not be found.
