Filter selection (2)

• A simple example:

      # $filter is a filter object
      $proxy->push_filter(
          response => $filter,       # only responses
          host     => 'example.com', # coming from example.com
          mime     => 'text/html',   # as HTML file
      );

• Naturaly, the ordering of filters is important, since each filter receives data chunks from its predecessor, possibly modifies them and passes them on to the next filter in the chain.

      # first, require authentication for everything
      $proxy->push_filter(
           request => $proxy_auth,  # 407 unless user is authenticated
      );
      # then modify example.com
      $proxy->push_filter(
         response => $filter,       # only responses
         host     => 'example.com', # coming from example.com
         mime     => 'text/html',   # as HTML file
      );
