HttpHeadersFilters

The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. It adds the Host header, scheme and port of the current request to any existing Forwarded header. To activate this filter set the spring.cloud.gateway.server.webmvc.trusted-proxies property to a Java Regular Expression. This regular expression defines the proxies that are trusted when they appear in the Forwarded header.

The RemoveHopByHop Headers Filter removes headers from forwarded requests. The default list of headers that is removed comes from the IETF.

It uses the Host header, scheme, port and path of the current request to create the various headers.

This regular expression defines the proxies that are trusted when they appear in the Forwarded header.
