Abstract: A method of providing web browsers with access to a foreign network via a network gateway device. The browsers are installed on clients of the gateway device and have different proxy settings. Web requests from a browser are intercepted during a browser pre-login phase. Based on the intercepted web requests, the browser is accommodated in configuring a proxy mode. The method includes intercepting and redirecting web requests from the proxy-mode-configured browser to provide access to the network. These steps are performed for each of a plurality of browsers installed on a single client.

Abstract: A method of redirecting a browser in a network. A fake IP address is provided to the browser in response to an attempt to resolve a non-resolvable DNS query by the browser for a destination address. The method also includes detecting a web request by the browser sent to the fake IP address, and redirecting the browser to a redirect address based on the detecting. Web requests sent to valid IP addresses may also be detected and redirected.
