There is no doubt that InterExt is an extremely fantastic extension, and it should be used on every Joomla site to control resources. It is very useful in boosting the speed of the site and reduce the server load and bandwidth. The great thing about this extension is that it is completely free.
The second great thing about it is that the Support from Developer is worth 10 Star rating.
I wish him a great success in future.
