This Filter is used to clean the Request and Response when proxying directly to another system. The purpose of this is to remove any routing metadata that we may have attached to it before sending it onwards.

GZip

fun GZip(compressionMode: GzipCompressionMode = Memory()): Filter

Basic GZip and Gunzip support of Request/Response. Only Gunzip responses when the response contains "content-encoding" header containing 'gzip'

RequestTracing

fun RequestTracing(startReportFn: (Request, ZipkinTraces) -> Unit = { _, _ -> }, endReportFn: (Request, Response, ZipkinTraces) -> Unit = { _, _, _ -> }, storage: ZipkinTracesStorage = ZipkinTracesStorage.THREAD_LOCAL): Filter

Adds Zipkin request tracing headers to the outbound request. (traceid, spanid, parentspanid)

ResetRequestTracing

fun ResetRequestTracing(storage: ZipkinTracesStorage = ZipkinTracesStorage.THREAD_LOCAL): Filter

Reset Zipkin request tracing. Use this to provide a new TraceId for every outbound call.

SetBaseUriFrom

fun SetBaseUriFrom(uri: Uri): Filter

Sets the base uri (host + base path) on an outbound request. This is useful to separate configuration of remote endpoints from the logic required to construct the rest of the request.

SetHostFrom

fun SetHostFrom(uri: Uri): Filter

Sets the host on an outbound request. This is useful to separate configuration of remote endpoints from the logic required to construct the rest of the request.

SetXForwardedHost

fun SetXForwardedHost(): Filter

Copy the Host header into the x-forwarded-host header of a request. Used when we are using proxies to divert traffic to another server.
