Blaze exposes a FHIR RESTful API under the default context path of /fhir. The CapabilityStatement exposed under /fhir/metadata can be used to discover the capabilities of Blaze. Everything stated there can be considered to be implemented correctly. If not please file an issue.
Blaze has to generate absolute URLs of its own in links and Location headers. By default Blaze assumes to be accessible under http://localhost:8080. The environment variable BASE_URL can be used to change this.
Besides the static BASE_URL setting, Blaze also respects the reverse proxy headers X-Forwarded-Host, X-Forwarded-Proto and Forwarded to generate its base URL dynamically.
