Question about Content-Length

Hi 

I hope that someone can help me with this matter. If I execute the
program "chunk" of the examples of the Library in this way:

chunk http://www.rpi.edu/

I got these headers:

HTTP/1.1 200 OK
Date: Wed, 24 Nov 1999 06:03:54 GMT
Server: Apache/1.2.5
Last-Modified: Thu, 18 Nov 1999 22:58:15 GMT
ETag: "a1600da-376b-38348487"
Content-Length: 14187
Accept-Ranges: bytes
Connection: close
Content-Type: text/html


When I execute:

chunk http://209.213.116.131/

the headers are:

HTTP/1.1 200 OK
Server: Microsoft-IIS/4.0
Date: Wed, 24 Nov 1999 06:04:39 GMT
Connection: close
Content-type: text/html


As you see the information of Content-Length is missing. How can I get
it using the Library?. 

Thanks for your help, suggestions and/or comments.
