Is there any other workaround for this problem?
Thanks...
Disallowing non-ASCII in headers isn't just a good idea, it's the law.
The HTTP 1.1 standard, RFC2616, allows only printable-ASCII in headers
(see section 4.2). The website is broken.
Can't tell you what to do if they won't make it HTTP-compliant. Not aware
of any choice other than to allow non-compliant headers from the whole
world. There may be ways to hack the INSPECT code to get exceptions for
limited sites, but I'm not aware of published instructions from Check
Point or third parties to do that.

Asunto: Re: [FW-1] Problem with a WebServer
Tell those folks to fix their web site. Allowing binary in a header is a
dangerous thing. We had this with one web site we used a lot after they did
a new site. Most of the graphics were missing, it looked horrible, links
didn't work, etc.
After I contacted them, they fixed the problem. They said they were using an
encrypted cookie and that was what was causing the problem. They changed it
so it only used ASCII and the site cleaned right up.

Subject: [FW-1] Problem with a WebServer
Date: Fri, 26 Aug 2005 14:31:04 -0500
Hi,
I have a problem with a WebServer running under a Checkpoint VPN-1 Pro NG
AI
R55.
The message in the log is:
Number: 344735
Date: 26Aug2005
Time: 13:11:31
Product: SmartDefense
Interface: eth1
Origin: FW-XXXX
Type: Log
Action: Reject
Protocol: tcp
Service: http (80)
Source: 10.10.146.205
Destination: 172.20.8.112
Source Port: 3738
Attack Name: Malformed HTTP
Attack Information: Non-ASCII character in HTTP header
Even though I tried to disable some rules at the SmartDefense and
WebIntelligence still gives this error.
Any clues?
