No, it’s not possible. What you’re asking for is not an HTTP request but a simple TCP connection like the one provided by ‘telnet’.
To do what you want, you can write a simple Java service - it should just take a few lines. The service would need 3 inputs: an object (data bytes), remote server address, remote server port. All you have to do is open a TCP socket to the remote endpoint and write the data out to it.
