• MogoHeaders - Welcome
  MogoHeaders uses a curl based interface to grab headers from websites. These headers can be extremly handy if finding out information such as if a site is down, or if a problem on the server could cause an interuption for some users. Headers can also tell you about the technology a site is using, and how it's redirection methods work. We allow you to change both the referer and useragent to get the best results!
