URL Redirects
The URL Redirects script configures the CacheFly CDN to issue HTTP redirects for specified paths, using the appropriate status codes. Each redirect status code dictates how browsers handle the redirect, thus shaping user experience and technical behavior.
To add a URL Redirects script config to the list of script configs created for your CacheFly services in general, or to associate a URL Redirects script config with a specific CacheFly service, see Adding and Using Script Configs.
Using the URL Redirects Script Config
In general, a URL redirect will cause a user originally connecting to one URL (or URI), to automatically connect instead to a second, different URL (or URI). For example, instead of accessing "/old/path/to/file.jpg", the user may be redirected to access "https://www.example.com/path/to/new/file.jpg".
The original access may be via the HTTP method GET or another ("non-GET") HTTP method such as PUT and POST. In the URL redirect, the HTTP method may be preserved or changed according to the type of redirect, which is in turn specified by the redirect code (HTTP response status code),
Redirect Codes and Usage:
301 Moved Permanently: This code is used for permanent URL changes. For GET methods, the method remains unchanged; other methods may be converted to GET. It is commonly used during the reorganization of a website.
302 Found: Indicates that the URL of the requested resource has been temporarily changed. GET methods remain unchanged; other methods may be converted to GET. Useful when a web page is temporarily unavailable for unforeseen reasons.
303 See Other: Primarily used to redirect after a PUT or POST operation. Ensures that all methods are converted to GET, preventing repeated operations when the user refreshes the result page.
307 Temporary Redirect: Similar to 302 but guarantees that the method and the body of the request are not changed, beneficial when the site offers operations beyond GET.
308 Permanent Redirect: Similar to 301, but it ensures that the method and body of the request are not changed at all, ideal for reorganizing websites while maintaining non-GET links/operations.
