Redirect_uri OAuth URL parameter can be used to retain the originally requested page so that a user can be redirected correctly after OAuth authorisation.
Explanation:
The open standard for token-based authentication on the Internet is OAuth (Open Authorization). OAuth, which is known as ' oh-auth, ' allows third-Party sites like Twitter to use account information on end users, without the user's password being revealed.
The redirect uri is an url used among OAuth services as a place to transmit the admin rights token by means of the redirect web browser.
Once the user authorises an application successfully, the approval manager must return the user to the client either with an authentication code or with an URL access token.
