In 12.1 sometimes we are seeing a strange header injected into the page
<html> <head> <title>Object moved</title> </head> <body> <h2>Object moved to <a href="/user/onboarding?ReturnUrl=%2Ff%2Fdiscussions%2F29185%2Ftest-shadow">here</a>.</h2>
Has anyone else seen this or have ideas what is injecting it into the page
