Why you might need this
User Agents are the self-reported names that HTTP client software reports itself as - as such they’re easily changed. While that is undisputably the case, in practice many bots and malicious scripts still report as the command line tools or HTTP libraries that they’re using to generate requests.
As an example, many vulnerability probe or scanning software will report as one of the Curl User Agents
This fact makes blocking user agent blocking a useful (if often underestimated) feature.
What you need to get started:
