NumberFormatException parsing HTTP-Header

[Malte Kempff]

Hi,
since a customer has changed his firewall, Proxy-Software and so on,
he gets Exceptions like this one below, when he tries to use our application
which performs RPC-calls via SOAP.

[SOAPException: faultCode=SOAP-ENV:Client; msg=Error parsing HTTP header
line "Content-Length: 3957  ": java.lang.NumberFormatException: 3957  ;
targetException=java.lang.NumberFormatException: 3957  ]

The customer uses now the hardware firewall "Netscreen" and an ISA Server
2000.

What can I do about it? Is this a bug of SOAP?

thanks in advance
