To perform customization it is necessary to first create a new, named ALG Banner Files object.
This new object automatically contains a copy of all the files in the Default ALG Banner Files
object. These new files can then be edited and uploaded back to NetDefendOS. The original Default
object cannot be edited. The following example goes through the necessary steps.

Uploading with SCP
It is possible to upload new HTTP Banner files using SCP. The steps to do this are:

first copied from the WebUI and pasted into a local text file which is then edited using an
appropriate editor.
Tip: Saving changes
In the above example, more than one HTML file can be edited in a session but the
Save button should be pressed to save any edits before beginning editing on another
file.
