Provides a directive to add expires headers to certain paths or headers
Add an expires block to your CaddyFile
expires {
match [a valid regexp] [1y1m1d1h1i1s]
match_header [header name] [a valid regexp] [1y1m1d1h1i1s]
}
Duration can be any combination of y(ear), m(onth), d(ay), h(our), i(minute), s(econd). Parts can be omitted but must remain in that order
If a path or header matches, an Expires header is set (don't forget to version your assets)
