Keep all your 301/302 managed within Craft. Very useful when using NGINX because you don't have an htaccess file! :(
The template for the route that you are redirecting from must not exist in order to successfully set up the redirect.
To use regex, simply wrap your "Match Uri" field with "#" (Example: "#^products(.*)#" will match products and products/anything-else)
For wildcards use an asterisk. (Example: "products*" will match products and products/anything-else)
Capture groups are just used by the standard $1, $2, ect. within your "Redirect To" field.
URI To Match: "#^products(.*)#"
Redirect To: "shop$1"
Note, we do not include the "/" because it will be part of the capture group
