Mod_proxy Chunk file size issue

[Anoop L <anpl1980@xxxxxxxxx>]

Hi,

I am using Apache HTTPD 2.2.17  + Mod_proxy + SSL on Ubuntu as a gateway. Everything works fine but when I send a request with Transfer Encoding: Chunked, it converts back if the file size  is too small. 

I tested with a 43k works fine. Tested with 16K and 5.5K it's getting converted as a request with 'content-length'.

My conf file:

<IfModule mod_ssl.c>

NameVirtualHost *:443

<VirtualHost *:443>

  ServerAdmin *

  ServerName  *

  DocumentRoot "/var/www"

   ErrorLog /var/log/apache2/error.log

        LogLevel warn

TransferLog /var/log/apache2/access.log

I had commented out lines which I had tried before.            

Any help would be appreciated.

Thanks,
