![]() If this is 0 (or any falsey value), no max age header will be sent.īrowsers send preflight requests before certain “non-simple” requests, to check they will be allowed. This sets the access-control-max-age header in preflight responses. The number of seconds the browser can cache the preflight response. If non-empty, these are declared in the access-control-expose-headers header.ĭefaults to. The list of extra HTTP headers to expose to the browser, in addition to the default safelisted headers. The default can be imported as _headers so you can extend it with your custom headers.įor example: from faults import default_headers CORS_ALLOW_HEADERS = ( * default_headers, "my-custom-header", ) CORS_EXPOSE_HEADERS: Sequence Sets the Access-Control-Allow-Headers header in responses to preflight requests.ĭefaults to: CORS_ALLOW_HEADERS = ( "accept", "authorization", "content-type", "user-agent", "x-csrftoken", "x-requested-with", ) ![]() The list of non-standard HTTP headers that you permit in requests from the browser.

Previously this setting was called CORS_ORIGIN_ALLOW_ALL, which still works as an alias, with the new name taking precedence. Generally you’ll want to restrict the list of allowed origins with CORS_ALLOWED_ORIGINS or CORS_ALLOWED_ORIGIN_REGEXES. Setting this to True can be dangerous, as it allows any website to make cross-origin requests to yours. Other settings restricting allowed origins will be ignored. Previously this setting was called CORS_ORIGIN_REGEX_WHITELIST, which still works as an alias, with the new name taking precedence. Useful when CORS_ALLOWED_ORIGINS is impractical, such as when you have a large number of subdomains.Įxample: CORS_ALLOWED_ORIGIN_REGEXES = CORS_ALLOWED_ORIGIN_REGEXES: Sequence]Ī list of strings representing regexes that match Origins that are authorized to make cross-site HTTP requests. Previously this setting was called CORS_ORIGIN_WHITELIST, which still works as an alias, with the new name taking precedence. The special value file:// is sent accidentally by some versions of Chrome on Android as per this bug.Įxample: CORS_ALLOWED_ORIGINS = The special value null is sent by the browser in “privacy-sensitive contexts”, such as when the client is running from a file:// domain. The origins in this setting will be allowed, and the requesting origin will be echoed back to the client in the access-control-allow-origin header.Īn Origin is defined by the CORS RFC Section 3.2 as a URI scheme + hostname + port, or one of the special values 'null' or 'file://'.ĭefault ports (HTTPS = 443, HTTP = 80) are optional.
