Guys There is a web request that i am receiving from

**Node : http in**  
\*\*GET : method \*\*  
**/msg\_stream : PATH ,**

URL : [http://localhost:1880/msg\_stream](http://localhost:1880/msg_stream)

When i get request, i need to response with "text/event-stream"

```auto
msg.headers['Content-Type'] = 'text/event-stream';
msg.headers['Cache-Control'] = 'no-cache';
msg.headers['Connection'] = 'keep-alive';
msg.headers['Transfer-Encoding'] = 'chunked';

```

What is the mean of it ?  
I need to send responses chunk by chunk to the client. Talking about Step by Step sending responses.  
Because of that i need, msg.res.write() function or alternative, but i do not have the necessary function in msg.res-\> . so I cant access it.

I can write global functions in settings.js file, BUT I have to pass the Response to the global function, there is only 1 response in msg object, it is msg.res, I think it is coming from express.js . I do not know How can I get access the Response of "msg.res" and cast it to another response type. Because msg.res do not contains neccessary methods that i need.  
OR i do not know how to send partially responses.

I need to write 3 writes

```auto
res.write("message 1 ")
res.write("message 2 ")
res.write("END")

```

Please help me, how can i do that. !

msg.res : list of functions .

```auto

function : (warn)
object
_res: [internal]
append: function
attachment: function
cookie: function
clearCookie: function
download: function
end: function
format: function
get: function
json: function
jsonp: function
links: function
location: function
redirect: function
render: function
send: function
sendfile: function
sendFile: function
sendStatus: function
set: function
status: function
type: function
vary: function

```

**Another question is that:**  
How can i get the content of the written function node "http Response" and "http in" , where the source code located ?  
may be i can manipulete the code or i can write my own nodes.

Hi @dysoft

Welcome to the forums.

The HTTP Response Node, does not (currently) support streaming responses, not sure if it's being worked on.

Maybe take a look at this, it uses SSE (Server Sent Events)  
NOTE: Have never used this Node, but may seem it will add the features you need. 🤷
