= HTTP
|
|
|
|
All HTTP based communication should be protected xref:features/exploits/http.adoc#http[using TLS].

|
|
Below you can find details around WebFlux specific features that assist with HTTPS usage.

== Redirect to HTTPS
|
|
|
|
If a client makes a request using HTTP rather than HTTPS, Spring Security can be configured to redirect to HTTPS.
|
|
|
|
For example, the following Java configuration will redirect any HTTP requests to HTTPS:
|
|
|
|
.Redirect to HTTPS
|
|
====
|
|
.Java
|
|
[source,java,role="primary"]
|
|
----
|
|
@Bean
|
|
SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
|
|
http
|
|
// ...
|
|
.redirectToHttps(withDefaults());
|
|
return http.build();
|
|
}
|
|
----
|
|
|
|
.Kotlin
|
|
[source,kotlin,role="secondary"]
|
|
----
|
|
@Bean
|
|
fun springSecurityFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
|
|
return http {
|
|
// ...
|
|
redirectToHttps { }
|
|
}
|
|
}
|
|
----
|
|
====
|
|
|
|
The configuration can easily be wrapped around an if statement to only be turned on in production.
|
|
Alternatively, it can be enabled by looking for a property about the request that only happens in production.
|
|
For example, if the production environment adds a header named `X-Forwarded-Proto` the following Java Configuration could be used:
|
|
|
|
.Redirect to HTTPS when X-Forwarded
|

SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {

http

// ...

|
|
.httpsRedirectWhen(e -> e.getRequest().getHeaders().containsKey("X-Forwarded-Proto"))
|
|
);
|
|
return http.build();
|

}
