Just to inform you:
In the new ATP 3.6.0 .htaccessmaker we see the new toggle: "Disable HTTP methods TRACE and TRACK (protect against XST)".
In the documentation you wrote:
Enabling this option will prevent remote clients from using the HTTP methods TRACE
and TRACK to connect to your site. These can be used by hackers to perform privilege
escalation attacks known as Cross Site Tracing (XST) [https://www.owasp.org/index.php/<br /> Cross_Site_Tracing]. To the best of our knowledge there are no side-effects to enabling this feature.
With our host Siteground: When setting this toggle to "yes" we get "500 Internal server error".
Don't know why. So definitely there are side-effects when enabling that feature.
