![]() The tenants commonly use the incoming host name to look up the correct back end for the customer tenant. This is because there's typically a shared pool of load balancers that accept incoming requests for all tenants. Multitenant PaaS services often require a registered and validated host name in order to route an incoming request to the appropriate tenant's back-end server. ![]() This value allows applications to determine the original host name, but only if they're coded to read these headers. In the latter case, the proxy often still sends the original host value in other HTTP headers, like Forwarded or X-Forwarded-Host. In this new session, it can either carry over the original host name of the client session or set a new one. ![]() A reverse proxy closes the client network session and sets up a new connection to the back end. In some scenarios, especially when there's an HTTP reverse proxy in the request chain, the original host header can get changed before it reaches the application server. The value is provided by the browser or some other user agent and can easily be manipulated by an end user. ![]() Never use the value of the host in a security mechanism. The host value is typically determined from the host component of the request URI, which the browser sends to the application as the Host HTTP header. It can be an IP address, but usually it's a name like (which the browser then resolves to an IP address by using DNS). In many cases, the application server or some component in the request pipeline needs the internet domain name that was used by the browser to access it. This requirement adds operational complexity when you deploy and renew certificates, but many PaaS services offer free TLS certificates that are fully managed. If you require end-to-end TLS/SSL (the connection between the reverse proxy and the back-end service uses HTTPS), the back-end service also needs a matching TLS certificate for the original host name. If your API implementation depends on cookies or generates absolute URLs, the guidance provided in this article does apply. Web APIs often don't return absolute URLs back to themselves, except in certain API styles, like OData and HATEOAS. They don't usually depend on cookies, unless you use cookies to secure communications between a single-page app and its back-end API, for example, in a pattern known as Backends for Frontends. Any description that includes the word ‘Virtual’ is not the information that is needed for creating an internet connection for you.Web APIs are generally less sensitive to the problems caused by host name mismatches. The wireless card information will follow the title of Wireless Lan adapter connection. Your IP address will be the IPv4 address.
