You can do this by logging onto the CensorNet server root, and typing:

nano /etc/squid/squid.conf

Then scroll down to the line that begins cache_dir directive and place a # in front of the line to comment it out, e.g.

#cache_dir ....

Save and exit the editor by using CTRL+X then Y followed by Enter.

You should then restart the squid process:-

/etc/init.d/squid restart

Please note: If you later use the System -> Configuration -> Proxy Cache Sizes option the on disk cache will be re-enabled and you will need to repeat this procedure.
