[undertow-dev] Server-Sent Event and HttpServerExchange

Hello, We are looking at the recent support of Server-Sent Events in Undertow, which looks great! We are using the HttpServerExchange to pass data through different handlers (we do it by passing these data via setting Attachments to the HttpServerExchange). Ultimately, we need these data, to determine what to push to the client via SSE. And as we don't have access to the HttpServerExchange from the ServerSentEventConnection, we are a bit stuck. We imagine we can code some « hack » to do so, but first, we were wondering if ever the dev team had some insights that could help us to implement the best solution that fits the « Undertow spirit » and our need. Thanks in advance for your answer. Best regards, Cédric. PS: may be passing data via Attachments of HttpServerExchange is not the best practice?
