mod_prox_http sends the HTTP header (all the headers) in a one go, although some filters in the chain may "fragment" it (like mod_ssl, but that'd be 16K packets per TLS record size max). > > Is there a way to increase the packet size to higher value like 64 KB in > mod_proxy.

It looks more like a limit on the system, TCP (send) buffers size? This is not something that can be forced on the mod_proxy side (no ProxySendBufferSize similar to SendBufferSize for the client connection), but it can be tuned by default on the system.
