-Response modification
-=====================
-
-This example shows how to modify the response produced by the ``iterator`` module.
-
-As soon as the iterator module returns the response, we :
-
-1. invalidate the data in cache
-2. modify the response *TTL*
-3. rewrite the data in cache
-4. return modified packet
-
-Note that the steps 1 and 3 are neccessary only in case, the python module is the first module in the processing chain.
-In other cases, the validator module guarantees updating data which are produced by iterator module.
-
-Complete source code

-.. literalinclude:: ../../examples/resmod.py
-   :language: python
-
-Testing
--------
-
-Run Unbound server:
-
-``root@localhost>unbound -dv -c ./test-resmod.conf``
-
-Issue a query for name ending with "nic.cz."
-
-``>>>dig A @127.0.0.1 www.nic.cz``
