Executes this command. Might modify variables. Must not modify the parameters.

It may handle conditional requests, except that if it replies with a status of HTTP.NOT_MODIFIED, it must still reply with a content (the same content that it would have returned for an inconditional request). This is because further SSI commands down the line may decide thay they have been modified, and then a content must be emitted by SSIResource.

Parameters:
request - the original HTTP request
parameters - The parameters for this command
variables - The global variables for the parse
Returns:
a Reply with the output from the command

 public int jumpTo(SSIResource resource,
                   CommandRegistry registry,
                   ArrayDictionary parameters,
                   Dictionary variables) throws ControlCommandException
