Can anyone please let me know, how to get this field in HTTP header ?
First, the browser or other client needs to request a byte range response. To do this, the client must use HTTP 1.1 with a Range header specifying the byte range it would like to receive from the server.
Next, the web server must be able to know the length of the response without having to buffer the entire response in memory before sending the response to the client. Certain types of content -- for example, content generated by CGIs -- or certain output filters may not allow this. I don't know which filters may cause problems, but if you see a "Transfer-Encoding: chunked" in your HTTP response headers, you may be experiencing this problem. In this case, try disabling/removing various filters (mod_include, mod_deflate) until you find the source of the problem. If your content is being generated by a CGI or other source of non-static content, see if having the CGI add a correct "Content-Length" response header helps. I apologize that I cannot be more specific here; maybe someone else can supply a more accurate answer.
There are no configuration directives that control the Content-Range behavior that I am aware of.
Here is an example showing how Content-Range is used:
$ telnet httpd.apache.org 80
