-## Bridge
-
-The Bridge filter route requests from one pipeline to other pipelines or HTTP proxies under an HTTP server.
-
-The upstream filter set the target pipeline/proxy in request header `X-Easegress-Bridge-Dest`. Bridge extracts the header value and tries to match it in the configuration. It sends the request if a destination matched and aborts the process if no match. It selects the first destination from the filter configuration if there's no header named `X-Easegress-Bridge-Dest`.
-
-Below is an example configuration with two destinations.
-
-```yaml
-kind: Bridge
-name: bridge-example
-destinations: ["pipeline1", "pipeline2"]
-```

 ## CORSAdaptor
 
 The CORSAdaptor handles the [CORS](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing) preflight request for backend service.
