    Description

      Gzip plugin gzips multiple times when you enable redirection by following settings or using escalate plugin.

      Enable redirection:
      CONFIG proxy.config.http.redirection_enabled INT 1
      CONFIG proxy.config.http.number_of_redirections INT 3

      Curl command output is provided below. Notice multiple "Content-Encoding: gzip" headers.

      curl -v -o/dev/null http://proxy-test:8080/get -H "Host: proxy-test" -x localhost:8080 -H "Accept-encoding: gzip"

      • About to connect() to proxy localhost port 8080 (#0)
