This field is reqauired by RFC 2616, which governs how HTTP clients, servers
and proxies behave.
In particular,
"14.45 Via
The Via general-header field MUST be used by gateways and proxies to
indicate the intermediate protocols and recipients between the user agent and
the server on requests, and between the origin server and the client on
responses. It is analogous to the "Received" field of RFC 822 [9] and is
intended to be used for tracking message forwards, avoiding request loops, and
identifying the protocol capabilities of all senders along the request/response
chain.
"
The word "must" in RFC parlance is an indication that this field falls squarely
into the LITFA category.

Subject: [isalist] Internet Explorer Headers
http://www.ISAserver.org
I have a client with ISA 2000 server, when the client access the internet
through the ISA 2000 firewall (cache mode or integrated mode) the
following are added to the header:
HTTP_VIA1.0 FIREWALL_SERVER
The client doesn't want this information being presented to the website
being visited.
I am certain that ISA can strip this information from outgoing requests,
but cannot seem to find it at the moment. Any help is welcome.
This is related to the following:
When viewing the page WWW.CENTRAAL.NL the name of the firewall server is
shown instead of the site name.
It would appear that this is related to the header information listed
above.
