# Build with release profile
cargo build --release

# Directory to save the cookies
cgit-gogs-auth-filter.cache-dir=/var/cache/cgit-gogs-auth-filter
# Time to live of the cookies in seconds
cgit-gogs-auth-filter.cookie-ttl=7200
# Url for access to the gogs service.
cgit-gogs-auth-filter.gogs-url=http://127.0.0.1:3000
