[release-branch.go1.20] net/http: validate Host header before sending Verify that the Host header we send is valid. Avoids surprising behavior such as a Host of "go.dev\r\nX-Evil:oops" adding an X-Evil header to HTTP/1 requests. Add a test, skip the test for HTTP/2. HTTP/2 is not vulnerable to header injection in the way HTTP/1 is, but x/net/http2 doesn't validate the header and will go into a retry loop when the server rejects it. CL 506995 adds the necessary validation to x/net/http2.
