You can add redirects by adding the website_redirects hook.

The optional field redirect_http_status will allow you to specify a custom HTTP status code to use for the redirect - if not specified, the fallback is 301

Examples

website_redirects = [
    # absolute location
    {"source": "/from", "target": "https://mysite/from"},

    # relative location
    {"source": "/from", "target": "/main", "redirect_http_status": 307},

    # use regex
    {"source": "/from/(.*)", "target": "/main/\1"}
]
