Spoofing your [[diy:user-agent-spoofing|User-Agent]] or [[diy:referrer-spoofing|Referer]] headers is a great way to familiarize yourself with the concept of manipulating this data.+Manually changing the values HTTP headers is fairly easy to do, and provides for some tactical opportunities on the field.

 +Header security is also a thing! Many websites are poorly developed, and use client-defined HTTP headers to delegate access to the system. The way to defend against this is making sure header inputs are sanitized and tested against spoofed headers, but not everyone does it.
