Is it possible to pass variables in a websocket $connect call?

Question

I have some existing code using Tomcat and Grizzly webservers, and they accept a path like the following:

```
wss:///forum/{subject}
```

It doesn't seem possible to configure API Gateway v2 endpoints to have variables such as subject here.  Is that correct or am I missing something?  
  
I realize that I _can_ work around this by sending messages, but it creates an inconsistency from the client perspective and there doesn't seem a good "reason" for it, except it hasn't been done yet.

Accepted Answer

Currently WebSocket API does not support path variables on $connect. You can send query string or custom header (if the client is non-browser) though.

Thanks.  
  
I wasn't actually able to get the headers approach to work; I'm not sure why, but I only seem to see a subset of the actual headers in the WebSocket lambda.  
  
The query parameters approach worked fine, though.
