Turim web serverį ir proxy serverį:
Web serveris pakeičia IP. Jis prisijungia , kada pasikeitė jo IP per NFS prie proxy serverio ir perrašo includinto
į httpd.conf failo turinį apie save , taip pat pakeičia b.html failo nuorodą.
We hae Apache and Apache Proxy: Web server changes IP, connect cia NFS to proxy, rewrites config and links inside html.
