it's about KeepAlive. Did you set somewhere downgrade-1.0 or force-response-1.0
The point of chunked encoding is that it's sent out only when a
number of conditions are met:
* The client supports chunked encoding
- This is implied by a client advertising itself as HTTP/1.1
- or by clients who explicitly send out the TE request header
(http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.39)
* The server cannot determine the content length.
- For a User-Agent using a protocol prior to HTTP/1.0, the content
simply will be sent out without a Content-Length header.
This means that it's very easy to provoke a chunked transfer-encoding
from a module producing dynamic content. |

We are not serving dynamic content but just the static content.

Apache 2 should allow chunked by default on 1.1 clients with Keepalives turned on.
--- edit ---
if you realy have to you can remove the content lengh header
| Code: |
Header unset Content-Length

| Did you monitor the headers? Apache error log? Apache version? |

I use wireshark to monitor recv network data.I find the data not chunked format. Apache also use content-length to send data.
I don't know how to configure. I search this question in google. But I can't find le solution. so I want to get help from here. |

You deliver the files by PHP or so? |
