How to disable reverse proxy?

Hello,

My configuration is as follows:
- Windows 2000 Server SP2
- ISA Server 2000 Standalone, acting as firewall and web proxy
- IIS 5.0 on the same machine

My problem is that, when I change a page on my web server, this change is
not refreshed on browsers accessing from Internet. I have tested "Routing
rules" in ISA Server configuration, but it seems that reverse proxy cannot
be disabled for that destination set. I also have restarted the web proxy
service, but the reverse cache is not refreshed.

The entry that is registered in the web proxy log file is:

xxx.xxx.xxx.xxx anonymous       Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 
5.0)
2001-10-17      17:32:29        W3ReverseProxy  yyy.yyy.yyy.yyy -       80      
-       299     90      http    TCP
GET     http://zzz.zzz.zzz.zzz/ text/html       NotModified     0       Rule1   
-

where xxx.xxx.xxx.xxx is the client IP address (public address of Internet),
yyy.yyy.yyy.yyy is the public IP address of the external network interface
and zzz.zzz.zzz.zzz is the private IP address of the internal web server
installed on the same machine as ISA Server is.

As you can see, this entry shows that the URL has not been modified, but it
really was. In fact, if I request the http://yyy.yyy.yyy.yyy/index.htm from
an external browser the right web page is sent back !!! So, it seems that
the original URL was cached and it cannot be refreshed, but I need it.

Do you know what may be the cause of the problem?

        Thank you.
