Can this help? Maybe an HTTP tunnel?

HTTP tunneling is a technique by which communications performed using various network protocols are encapsulated using the HTTP protocol, the network protocols in question usually belonging to the TCP/IP family of protocols. The HTTP protocol therefore acts as a wrapper for a channel that the network protocol being tunneled uses to communicate.

The HTTP stream with its covert channel is termed an HTTP tunnel.

HTTP tunnel software consists of client-server HTTP tunneling applications that integrate with existing application software, permitting them to be used in conditions of restricted network connectivity including firewalled networks, networks behind proxy servers, and network address translation.
