Problem: double slashes in a request can cause the request not to resolve

Any request that contains a two (or more) consecutive slashes can result in a 404 error. For example/hello//world/. The problem in this example is the "//" betweenhello andworld.

Solution: filter for double slashes

Apply a configuration to your Istio ingress to filter for double slashes in requests and replace them.

1. Create a new configuration file namedapigee-merge-slash-filter.yaml.
2. Paste the following content into the file:

   apiVersion: networking.istio.io/v1alpha3kind: EnvoyFiltermetadata:  name: apigee-merge-slashes  namespace: istio-systemspec:  workloadSelector:    labels:      app: istio-ingressgateway  configPatches:  - applyTo: NETWORK_FILTER # http connection manager is a filter in Envoy    match:      context: GATEWAY      listener:        filterChain:          filter:            name: "envoy.http_connection_manager"    patch:      operation: MERGE      value:        typed_config:          "@type": "type.googleapis.com/envoy.config.filter.network.http_connection_manager.v2.HttpConnectionManager"          merge_slashes: true

3. Apply the configuration with the following command:

   kubectl apply -f apigee-merge-slash-filter.yaml
