Hello, is there a documentation on ktor or a sample to proxy in image, receive this image and send it to the client directly  please ?

If you are looking for a reverse proxy. Take a look at this: <https://github.com/ktorio/ktor-exercises>

In this example, the program wait to have the entire file before send it… Is it possible to do this as and when. When we receive a bit we send it etc until the file is finish ?

 Yes it is possible you have to pipe streams. I thought it was doing that already but it seems that i didn’t remember it well

Im in holidays and i do not have a computer right now so i cannot update the sample or tell you exactly how

Ok I understand, if you find an example after your holidays it can be very useful for me ! Have good holidays :slightly_smiling_face:

Maybe this could help:
```
val body = client.get&lt;ByteReadChannel&gt;(...)
call.respond(
  HttpStatusCode.OK, 
  object: OutgoingContent.ReadChannelContent() {
      override fun readFrom(): ByteReadChannel = body
})
```

That works, thank. But how to be sure that send byte by byte and not everything in one request ?

`ByteChannel` size is limited. There is no way to keep more than 4k bytes there.

So you could write a test with size &gt;4kb

Ok perfect, thank you very much for your help !
