range-diff shows what a rebase actually changed

After a force push the reviewer's question is "what changed since I looked". A normal diff between the two branch tips is useless because the base moved. range-diff compares the two series commit by commit.

git range-diff main feat@{1} feat

It shows which commits are identical, which were reworded, and the diff of the diff for the ones that changed.

Session cookies: HttpOnly, Secure, SameSite=Lax

securityhttp

Three attributes, each closing a class of attack. HttpOnly keeps scripts from reading it. Secure keeps it off plain HTTP. SameSite=Lax stops it being sent on cross-site POSTs, which is most CSRF.

Set-Cookie: session=...; HttpOnly; Secure; SameSite=Lax; Path=/; Max-Age=1209600

Strict breaks arriving from an external link while logged in. Lax is the default worth keeping.
