Uptime Robot, by default, sends all HTTP requests with pre-defined HTTP headers.

Now, it is possible to customize this totally with the “Custom HTTP Headers” feature that can be found in the Pro Plan’s “Add/Edit Monitor Dialog>Advanced>Custom Headers” option.

Custom HTTP Headers

Sample use cases:

  • For monitoring the mobile version of a web page, we can use a mobile “User-Agent” header to force the site to serve the mobile content.
  • The site may be requiring/expecting various authorization HTTP Headers
  • We may want to white-label the requests and change the User-Agent to a custom one

Hope it helps for a better monitoring :).

Can you please just publish a tutorial step by step on how exactly can we set a proper Custom HTTP Header to a website that does not show UP?

Thanks!
