When handling a redirect response that has a relative location,

we try to build the new URL with ServerInfo.buildFromUri

which fails with a relative location (e.x.: /foo)

We should either: Have a better error that relative URIs are not supported to follow redirects, or make the redirect enrich the URI with the absolute part of the HttpRequestContext

Brief description:
After "connecting" to the BackEnd the idle-timeout seems to cause the connection to crash - which should probably not happen. I have also tried to set the idleTimeoutMills and totalRequestTimeoutMills to higher values like 10000 ms - same issue.

Reproducability:

Version 3.0.18
Code:

SseClient sseClient= httpClient.createSSE("https://datagate.dev:6040/api/v1/events")
                .addHeader("Authorization", "Bearer " + APIConnection.token)
                .build()
                .execute(new SseClientCallback() {
            @Override
            public void onConnect() {
                logger.info("Connected to the SSE-Backend!");
            }

            @Override
            public void onDisconnect() {
                logger.info("Disconnected from the SSE-Backend!");
            }

            @Override
            public void onError(Throwable throwable) {
                logger.error("SSE-Error: " + throwable.toString());
                throwable.printStackTrace();
            }
}
