request_header_filter #

Description #

The request_header_filter is used to filter traffic based on request header information.

Configuration Example #

A simple example is as follows:

flow:
  - name: test
    filter:
      - request_header_filter:
          include:
          - TRACE: true

The above example shows that requests are allowed to pass through only when the headers of the requests contain TRACE: true.

curl 192.168.3.4:8000 -v -H 'TRACE: true'
