java.lang.Object | +--sunlabs.brazil.proxy.CookieFilter
The CookieFilter keeps a
 record of all the browser cookies associated with a given session.
 This can be
 used to make the user's cookies "mobile" as follows.  A user's cookies
 are normally stored with the browser being used, on the user's machine.
 If the user runs a different browser or goes to a different machine, the
 user's cookies will not be there.  Instead, the user can access the web
 via a proxy that keeps all their cookies.  No matter which browser the
 user chooses or machine the user is at, a proxy running with the
 CookieFilter will automatically remember and add in their
 appropriate cookies.  The CookieFilter also supports
 multiple, concurrent users, keeping each user's cookies separate.
 
document.cookie = "userid=778287312".  Any and
 all Javascript is passed unchanged by this filter.
 CookieFilter.

public boolean init(Server server,
                    String prefix)
Handler
init in interface Handlerserver - The HTTP server that created this Handler.
		Typical Handlers will use Server.props
		to obtain run-time configuration information.prefix - The handlers name.
		The string this Handler may prepend to all
		of the keys that it uses to extract configuration information
		from Server.props.  This is set (by the Server
		and ChainHandler) to help avoid configuration parameter
		namespace collisions.
true if this Handler initialized
		successfully, false otherwise.  If
		false is returned, this Handler
		should not be used.
public boolean respond(Request request)
                throws IOException
Handler
respond in interface Handlerrequest - The Request object that represents the HTTP
		request.
true if the request was handled.  A request was
		handled if a response was supplied to the client, typically
		by calling Request.sendResponse() or
		Request.sendError.
IOException - if there was an I/O error while sending the response to
		the client.  Typically, in that case, the Server
		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 a
		FileNotFoundException due to not being able
		to open a file).  In that case, the Handler's
		duty is to turn that IOException into a
		HTTP response indicating, in this case, that a file could
		not be found.
public boolean shouldFilter(Request request,
                            MimeHeaders headers)
shouldFilter in interface Filterrequest - The in-progress HTTP request.headers - The MIME headers generated by the wrapped Handler.
true if this filter would like to examine and
		possibly rewrite the content, false otherwise.
public byte[] filter(Request request,
                     MimeHeaders headers,
                     byte[] content)
filter in interface Filterrequest - The finished HTTP request.headers - The MIME headers generated by the Handler.content - The output from the Handler that this
		Filter may rewrite.
Filter may return
		the original content unchanged.  The
		Filter may return null to indicate
		that the FilterHandler should stop processing the
		request and should not return any content to the client.|
