A problem with such systems is that the availability and content retrieval time depend on availability and speed of the Internet connection. In this book, we present a module which dynamically configures the BINDv9.x DNS server in a way that the DNS server replies the closest server¿s IP address respective to the user¿s location. The re-director can operate using three policies which makes the module customizable for different environments. Each policy uses different criteria to redirect a user to the closest server.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659690150\"\u003e\u003ch3\u003eA common problem to the most of the web-based services with solution as a reliable DNS based redirection mechanism\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659690150","offer_id":39434599235677,"sku":"9783659690150","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/90eb0c4a-8f4b-4ae5-ac5c-5857736b33da.jpg?v=1773469756","url":"https:\/\/shop.autorenwelt.de\/products\/concept-for-a-dns-based-redirection-mechanism-for-educational-portals-a-common-problem-to-the-most-of-the-web-based-services-with-solution-as-a-reliable-dns-based-redirection-mechanism-von-mohammad-rafi-bahez","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
