Filter selection (3)

• Filters sharing the same match routine can be pushed within a single call:

      $proxy->push_filter(
          host     => 'example.com',
          request  => $req_filter,
          response => $res_filter,
          response => $res_filter2,
      );

• In this example,

  • $req_filter is applied on all requests to example.com

  • $res_filter receives the response body data for all requests to example.com before $res_filter2

• The filter class is used by the proxy to decide if the filter is a header filter or a body filter
