Abstract
A method and system is presented for bypassing a local Domain Name Server (DNS) when using edge caching servers. Domain names of frequently used business applications that are known to rely upon edge servers, together with the corresponding authoritative DNSs, are listed in both local hosts file and user defined FSFD local configuration file fsfd.conf. When the client computer's browser attempts to resolve a domain name, a File System Filtering Driver (FSFD) in the client computer intercepts the browser's request. If the domain name which is being resolved is found in a local FSFD configuration file fsfd.conf, then the FSFD initiates a DNS request directly to the appropriate authoritative DNS whose IP address gets extracted from the fsfd.conf record, thus bypassing the local DNS. The authoritative DNS returns the IP address for an edge caching server that is topographically proximate to the client computer's browser.
