|

</H2>
|
|
|
|
<P>ISA Server provides many important networking functions that include Firewalling,
|
|
Web-cache, Policy-based Administration, Dynamic IP Filtering, VPN Support, Intrusion
|
|
Detection, NAT and reporting. While being a robust solution for Windows-based clients,
|
|
its a pain for Linux users because most of the Linux-based browsers do not
|
|
appear to be working behind it. The term 'appear to be' is used because there are some
|
|
known workouts for this.
|
|
<H2><A NAME="ss2.2">2.2 Why doesn't it work?</A>
|
|
</H2>
|
|
|
|
<P>While running Windows-based clients behind ISA Server, have you noticed that normally
|
|
you could browse using only Internet Explorer, and not using other browsers like
|
|
Netscape? This is because ISA server uses an authentication mechanism it
|
|
calls 'Integrated Authentication.' When Internet Explorer contacts ISA server to
|
|
request a page, along with every request it sends a hash that the server uses to
|
|
authenticate you as a legitimate domain user [You can verify this fact by sniffing
|
|
some packets while you browse, just check the request header that your browser
|
|
sends to the ISA server]. This authentication method is not supported by other
|
|
browsers, which is why it renders most of the browsers useless.
|
|
<P>The following sections will tell you about two methods to enable your Linux-based
|
|
browser to browse the net.
