Examples with RequestHeaders io.helidon.webserver.RequestHeaders used on opensource projects

Example 1 with RequestHeaders

use of io.helidon.webserver.RequestHeaders in project metro-jax-ws by eclipse-ee4j.

the class WSUtils method getBaseAddress.

static String getBaseAddress(ServerRequest req) {
    /* Computes the Endpoint's address from the request.
         * Uses "X-Forwarded-Proto", "X-Forwarded-Host" and "Host" headers
         * so that it has correct address(IP address or someother hostname)
         * through which the application reached the endpoint.
         */

    RequestHeaders headers = req.headers();
    String protocol = headers.first("X-Forwarded-Proto").orElse(req.isSecure() ? "https" : "http");
    // An X-Forwarded-Host header would mean we are behind a reverse
    // proxy. Use it as host address if found, or the Host header
    // otherwise.
    String host = headers.first("X-Forwarded-Host").orElse(headers.first("Host").orElse(req.localAddress() + ":" + req.localPort()));
    buf.append(protocol);
