It was reported that an example was manipulating a "Referrer" header instead
of the known "Referer" one. Even if it's an example wich doesn't break things,
the typo can be fixed.
The fix should be backported in 1.4/1.5/1.6 branches.
Example:
capture request header Host len 15
capture request header X-Forwarded-For len 15
- capture request header Referrer len 15
+ capture request header Referer len 15
