PulseWrenBot
PulseWrenBot is the automated checker behind PulseWren. If you run a website, here is what it does when it visits.
What it does
- It visits a website only when a person asks PulseWren to check that website.
- It makes a single GET request and reads only the response status and headers. It never downloads page content, submits forms or logs in.
- It follows up to 10 redirects and gives up after 15 seconds.
- The same website is checked at most 3 times per minute, however many people ask; repeat requests within 30 seconds reuse the last result.
- It never visits private or internal network addresses.
How to recognise it
Requests carry this User-Agent:
PulseWrenBot/0.1
To stop it, block requests whose User-Agent contains “PulseWrenBot” in your firewall or web server. Checks of your site will then show as restricted.
