How do I force apache to deliver a file in chunked encoded format

apache chunked-encoding

I am verifying if my application handles file content delivered through chunked-encoding mode. I am not sure what change to make to the httpd.conf file to force chunked encoding through Apache. Is it even possible to do this with Apache server, if not what would be an easier solution? I am using Apache 2.4.2 and HTTP 1.1.

By default, keep-alive is On in Apache and I do not see the data as chunked when testing with wireshark.

Only way I managed to do this was by enabling the deflate module. Then I configured my client to send "Accept-Encoding: gzip, deflate" header and apache would compress and send the file back in chunked mode. I had to enable the file type in the module though. AddOutputFilterByType DEFLATE image/png

See example:

curl --raw -v --header "Accept-Encoding: gzip, deflate" http://localhost/image.png | more
* Connected to localhost (127.0.0.1) port 80 (#0)
> GET /image.png HTTP/1.1
> User-Agent: curl/7.35.0
> Host: localhost
> Accept: */*
> Accept-Encoding: gzip, deflate
