gzip and deflate in .htaccess

Question

Is it possible to use both gzip and deflate or do we have to only use one of them in .htaccess

eg

<ifModule mod_gzip.c>
...
</ifModule>


<IfModule mod_deflate.c>
...
</IfModule>

.. I saw a previous question that explains the difference but I am unsure if we could use both together or not.
