For certain monitor types, we allow you to set a user agent in the Advanced tab of the monitor settings. The user agent you choose is then passed along with the HTTP request, which informs the receiving server about the “user’s” environment. For example, using the appropriate user agent, we can tell the server that we’re using Chrome 83 on a Windows platform. This could prompt the server to send specific content, optimized for that environment.
In addition to allowing custom user agents, the user agent option in the monitor setting came with a predefined list of commonly used user agents. We felt this list was getting a bit outdated, so we’re extending it in this release. The newly updated list of predefined user agents now contains the correct user agents for recent versions of most modern browsers.
