As you can see theres nothing related to IP numbers.

Unless you substituted (domain.net) for 165.193.172.182, 213.174.196.170 or www.easyjet.com or *.easyjet.com there's is nothing in your routing script that would refer to the destination site in question.

CARPExceptions=new MakeCARPExceptions();
cCARPExceptions=0;
function MakeNames(){
this[0]="*.domain.net";
this[1]="domain.net";

Perhaps creating the anonymous HTTP (and HTTPS if necessary) access rule to a domain name set that includes www.easyjet.com is the most reasonable solution for you.

Yep htat is the only way but it will require me to create the rule for each site that has the same problem. I think that it is related more to IE7 than to ISA.

You may very well be right that it's related to how IE7 and ISA are handling the proxy authentication request/response relationship.  Is your ISA web proxy only configured to support windows integrated authentication? Or are you also allowing Basic Authentication? 

Is IE7 loaded with the most recent MS patches?
What Proxy authenication settings are configured in IE7?

Hi, I have integrated and Basic authentication methods enabled on ISA for internak network. I think I enabled Basic a few months ago when this problem started, trying to sort it out if Isa just can ask me for the authentication.

We use WSUS and I am sure that IE7 have almost the  99% of updates available from MS, and the proxy authentication settings in IE7 are set by FW client. Under Lan Settings in Connection Tab we have all the options checked.

Have you have looked at this topic?
http://forums.isaserver.org/m_2002033963/mpage_1/tm.htm

Also, are you able to replicate this problem with another web browser, such as firefox ?

Yes I saw this post before when researching for information and so "Enabled Windows Integrated Authentication" in IE7 Advanced Options"  is disabled on my IE7. But it didnt solve anything :(


I will install Firefox and let you know what happens.

I have installed Firefox and it works properly. It displays all the things in easyjet.com and I can search for available flights.

Yet another reason why I don't want care to see IE7 behind an ISA Server environment that requires User Authentication for HTTP/HTTPS Access rules, it just seems to be too much of a wildcard.  Although if I were forced to make it work, I'd probably look at this situation from a different perspective.

So .... Are you going to create an all users access rule to that destination?

I dont think it is worthy because it happens in more sites as wikipedia.org, ...

As soon as everyone has IE7 on the company Ill disable all the checks and leave only checked "Use a web proxy server" in the Proxy settings.

Thanks for the help.
