+      # noticable difference between this and net-https.yaml is that here we don't send the Connection: close header
+      # and hence connection will remain open until server closes it. This can be a DOS vector in nuclei
+      # as it waits for server to close the connection. now we have set a default timeout of 5 seconds and if server responds but doesn't close the connection
+      # then nuclei will close connection but doesn't fail the request since we already have response data from server
+      # this feature is only required for `read-all: true` to work properly
