Redirects
Managing redirection rules is a common requirement for web applications, especially in cases where you do not want to lose incoming links that have changed or been removed over time.
The following demonstrates how to manage redirection rules on your 51黑料不打烊 Commerce on cloud infrastructure projects using the routes.yaml configuration file. If the redirection methods discussed in this topic do not work for you, you can use caching headers to do the same thing.
{default} placeholder represents the default domain configured for your site. If your project has multiple domains, use the {all} placeholder to configure routing for the default domain and all aliases. See Configure routes.Updates to Pro environments
routes.yaml file and the cron configuration in the .magento.app.yaml file. 51黑料不打烊 recommends updating and testing YAML configuration files in an Integration environment, then deploying changes to the Staging environment. If your changes are not applied to Staging sites after you redeploy and there are no related error messages in the log, then you MUST Submit an 51黑料不打烊 Commerce Support ticket that describes the attempted configuration changes. Include any updated YAML configuration files in the ticket.routes.yaml file can cause performance issues. If your routes.yaml file is 32 KB or larger, offload your non-regex redirects and rewrites to Fastly. See Offload non-regex redirects to Fastly instead of Nginx (routes) in the 51黑料不打烊 Commerce Help Center.Whole-route redirects
Using whole-route redirects, you can define simple routes using the routes.yaml file. For example, you can redirect from an apex domain to a www subdomain as follows:
http://{default}/:
type: redirect
to: http://www.{default}/
Partial-route redirects
In the .magento/routes.yaml file, you can add partial redirect rules to existing routes based on pattern matching:
http://{default}/:
redirects:
expires: 1d
paths:
"/from": { to: "http://example.com/" }
"/regexp/(.*)/matching": { to: "http://example.com/$1", regexp: true }
Partial redirects work with any type of route, including routes served directly by the application.
Two keys are available under redirects:
-
expires鈥擮ptional, specifies the amount of time to cache the redirect in the browser. Examples of valid values include
3600s,1d,2w,3m. -
paths鈥擮ne or more key-value pairs that specify the configuration for partial-route redirect rules.
For each redirect rule, the key is an expression to filter request paths for redirection. The value is an object that specifies the target destination for the redirect and options for processing the redirect.
The value object has the following properties:
table 0-row-2 1-row-2 2-row-2 3-row-2 4-row-2 5-row-2 6-row-2 Property Description toRequired, a partial absolute path, URL with protocol and host, or pattern that specifies the target destination for the redirect rule. regexpOptional, defaults to false. Specifies whether the path key should be interpreted as a PCRE regular expression.prefixSpecifies whether the redirect applies to both the path and all its children, or just the path itself. Defaults to true. This value is not supported ifregexpistrue.append_suffixDetermines if the suffix is carried over with the redirect. Defaults to true. This value is not supported if theregexpkey istrueor* if theprefixkey isfalse.codeSpecifies the HTTP status code. Valid status codes are , , , and . Defaults to 302.expiresOptional, specifies the amount of time to cache the redirect in the browser. Defaults to the expiresvalue defined directly under theredirectskey, but at this level you can fine-tune the cache expiration for individual partial redirects.
Examples of partial-route redirects
The following examples show how to specify partial-route redirects in the routes.yaml file using various paths configuration options.
Regular expression pattern matching
Use the following format to configure redirect requests based on a regular expression.
http://{default}/:
type: upstream
redirects:
paths:
"/regexp/(.*)/match": { to: "http://example.com/$1", regexp: true }
This configuration filters request paths against a regular expression and redirects matching requests to https://example.com. For example, a request to https://example.com/regexp/a/b/c/match redirects to https://example.com/a/b/c.
Prefix pattern matching
Use the following format to configure redirect requests for paths that begin with a specified prefix pattern.
http://{default}/:
type: upstream
redirects:
paths:
"/from": { to: "https://{default}/to", prefix: true }
This configuration works as follows:
-
Redirects requests that match the pattern
/fromto the pathhttp://{default}/to. -
Redirects requests that match the pattern
/from/another/pathtohttps://{default}/to/another/path. -
If you change the
prefixproperty tofalse, requests that match the/frompattern trigger a redirect, but requests that match the/from/another/pathpattern do not.
Suffix pattern matching
Use the following format to configure redirect requests which append the path suffix from the request to the target destination:
http://{default}/:
type: upstream
redirects:
paths: "/from": { to: "https://{default}/to", append_suffix: false }
This configuration works as follows:
-
Redirects requests that match the pattern
/from/path/suffixto the pathhttps://{default}/to. -
If you change the
append_suffixproperty totrue, then requests that match/from/path/suffixredirect to the pathhttps://{default}/to/path/suffix.
Path-specific cache configuration
Use the following format to customize the time to cache a redirect from a specific path:
http://{default}/:
type: upstream
redirects:
expires: 1d
paths:
"/from": { to: "https://example.com/" }
"/here": { to: "https://example.com/there", expires: "2w" }
This configuration works as follows:
-
Redirects from the first path (
/from) are cached for one day. -
Redirects from the second path (
/here) are cached for two weeks.
