I do similar operations where the reply contains the size in the metadata in FIX data.
I use the following:
MSG_PEEK
This flag causes the receive operation to return data from the
beginning of the receive queue without removing that data from
the queue. Thus, a subsequent receive call will return the same
data.
Then you can get the content-length and work out how much to read, then use
MSG_WAITALL(since Linux 2.2)
This flag requests that the operation block until the full
request is satisfied. However, the call may still return less
data than requested if a signal is caught, an error or disconā
nect occurs, or the next data to be received is of a different
type than that returned.

NAME
corkscrew - Tunnel TCP connections through HTTP proxies
SYNOPSIS
corkscrew PROXY PROXYPORT TARGETHOST TARGETPORT [AUTH_FILE]
DESCRIPTION
corkscrew is a simple tool to tunnel TCP connections through an HTTP proxy supporting the CONNECT method. It reads stdin and writes to std-
out during the connection, just like netcat. It can be used for instance to connect to an SSH server running on a remote 443 port through a
strict HTTPS proxy.
PROXY
The name of the host running the HTTP proxy.
PROXYPORT
The port on which to connect on the proxy.
TARGET
The host to reach through the proxy.
TARGETPORT
The port to connect to on the target host.
AUTH_ FILE
The auth file is made of one single line containing your username and password in the form
username:password
OPTIONS
None.
EXAMPLES
The common usage of corkscrew is to put the following line in ~/.ssh/ssh_config:
ProxyCommand corkscrew proxy proxyport %h %p [<path to auth_file>]
This will let the ssh connection go through the proxy with the help of corkscrew.
ENVIRONMENT
None.
FILES
None.
SEE ALSO
ssh_config(5)
