Example
An example of applying a Feature-Policy based on the major part of a particular
browser's version number:
declare local var.browser_version INTEGER;
if (client.browser.name != "" && client.browser.version != "") { # capture just the major version set var.browser_version = std.atoi(if (client.browser.version ~ "^([0-9]+)", re.group.1, "0"));
# A vulnerability in WebUSB in Chrome was fixed in v73, # so disable USB in any version earlier than that if (client.browser.name == "Chrome" && var.browser_version < 73) { add resp.http.Feature-Policy = "usb 'none'"; }}
