Re[6]: HTTP :unsupported content-encoding of '' found

I followed the answers from the server fo a few days and found that 
sometimes the server sends no Content-Encoding and I still get this 
error - "HTTP :unsupported content-encoding of ''".
Down there is a header received from the server with this error and 
without Content-Encoding. Why is Axis assuming an empty Content-Encoding 
when the headers contain no Content-Encoding?
The answer contains a Authorization field that should not be present in 
the server response.
I don't know why but everytime when I receive "unsupported 
content-encoding" the response header contains a Authorization field,  a 
OSCP_RESPONSE and a lot of other fields that are not in a usual SOAP 
response.
