htaccess/uppercase-rewrite-flags
Severity: warning · Status: enforced · Applies to: ids/**/.htaccess
What
Write flags as [R=302,L], not [r=302,l].
Why
Apache accepts either spelling, so nothing is broken. Upper case is what the mod_rewrite documentation uses, and it is what a reviewer reading the file expects — a lower-case flag list reads as a typo and costs a moment's double-take every time somebody looks at it.
This is the mildest rule in the set. It is here because it is free to fix.
Wrong
RewriteRule ^$ https://example.org/ [r=302,l]Right
RewriteRule ^$ https://example.org/ [R=302,L]How to fix
Upper-case the flag names. Values keep their own case where they have one.
