Problem
There is following code in example box

# Example of exclusion from mapping, logo.gif won't be displayed
# /web-console/images/logo.gif=*

Neverthees, this code means that any of workers can handle logo, not that logo is excluded.

Solution
To demnostrate exlusion add ! on the biggining of in line in the example (after comment of course):

# !/web-console/images/logo.gif=*
