Exclude URLs from this report
Hide findings on pages you are not responsible for — a section another team owns, or legacy pages out of contract. One pattern per line: a plain substring that matches anywhere in the URL (/medicare/, .aspx) or a slash-wrapped /regex/ (/medicare|medicaid/i); # comments are ignored. A finding is hidden when every affected page matches; for findings with more than 25 pages this is judged by the listed sample. This only changes what this report shows in your browser — every page is still scanned, and your list is saved on this device.
