(1) In e-mail, a redirect is an option found in e-mail clients that is similar to a forward, with the exception that the body of the text is not normally shown as quoted text. Additionally the From (or) Sender field will show the e-mail address of the original sender, and in brackets it will show your information. For example if you received the e-mail from "email@example.com" and your e-mail address is "firstname.lastname@example.org", when you redirect this e-mail to another recipient, the From (or) Sender information might read something like this:
From: email@example.com ( by way of "Your Name" )
(2) Redirect also refers to a Web server function where an old URL can be redirected to a new one. There are a series of redirect HTTP response codes that a server can return, including the following:
- 301: (permanent) Returns a permanent redirect status indicating that the resource has moved permanently.
- 302: (temp) Returns a temporary redirect status. This is the default.
- 303: (seeother) Returns a "See Other" status indicating that the resource has been replaced.
- 410: (gone) Indicates that the resource has been replaced.
