Dynamic data chunking for WAN optimization byte caching
Dynamic data chunking helps to detect persistent data chunks in a changed files or in data embedded in traffic using an unknown protocol. For example, Lotus notes uses a private protocol to transfer email attachments in crafted messages. Dynamic data chunking performs byte caching of data in Lotus notes traffic. Dynamic data chunking is available for HTTP, CIFS and FTP.
Use the following command to enable dynamic data chunking for HTTP in the default WAN optimization profile.
config wanopt profile
edit default
config http
set prefer-chunking dynamic
end
By default, dynamic data chunking is disabled and prefer-chunking is set to fix.
