Apply changes to http handlers on fly without server restart
This has been implemented by simply restarting http servers in case of http_handlers directive in configuration xml had been changed. But, for this I have to change the handlers interface to accept configuration separatelly, since the configuration that contains in the server is the configuration with which server had been started.
