Hi,

I’m newbie Wowza module developer.

I face on problem in my project.

**I want to return some custom response message. when rtpSession rejected.** (like http response body)

But i can’t find method or can control handle in RTPSession object.

in describe this project

Client have to connect Wowza server like this : rtsp://[Wowza-IP]:1935/live/?ID=12345&PubPoint=mystream

but, if client use connect URL like this : rtsp://[Wowza-IP]:1935/live/?PubPoint=mystream

I want to control return custom response message like this.(if i can control more lower level)

```auto
RTSPBufferedWriter.write("RTSP/1.0 [COLOR="#FF0000"]400[/COLOR] OK" + CRLF);
RTSPBufferedWriter.write("Public: DESCRIBE, SETUP, PLAY, PTIONS" + CRLF);
RTSPBufferedWriter.write("CSeq: " + RTSPSeqNb + CRLF+ CRLF);
RTSPBufferedWriter.write("[COLOR="#FF0000"]Parameter ID - required[/COLOR]"+ CRLF);
RTSPBufferedWriter.flush();

```

The red font is custom return Code & message.

Is there are something way to resolve this issue?

Constraint

This project have to use RTSP protocol(we can’t change other protocol http, rtmp).

You might try [redirecting](https://www.wowza.com/docs/how-to-redirect-an-http-or-rtsp-session-through-server-side-code) the session:

```auto
rtpSession.redirectSession([your-url])

```

There is not a way to do this in Wowza with RTSP clients, like there is with RTMP clients.

Thank you matt\_y.

But, you miss my point in my post.

I want to know how can i retrun custom response message. **when rtspsession reject**. not a redirection.
