HTTP Redirection

Introduction

About this Document

In this document, we explain how to configure the reverse proxy to automatically redirect HTTP traffic to HTTPS. When you add an SSL certificate to your website, the URL scheme used by visitors changes from HTTP to HTTPS. The S means that the connection is secure. After adding an SSL certificate, you can redirect all HTTP requests to the HTTPS version of your site. For example, if someone visits http://www.example.com/ they will automatically be redirected to https://www.example.com/

Configuration Overview

  • Create the HTTPS reverse proxy entry as explained in the reverse proxy manual (port 443).

  • Select the newly created entry and click on edit as new.

  • Add a new HTTP entry for the same application server (port 80). Don’t add certificates and make sure to disable secure connections.

  • Select the Security tab. Under Request Filtering find the Allowed Requests field.

  • Copy and paste the following text into the Allowed Requests field:

/(.*) https://www.example.com/$1 [R=301,L]

Replace www.example.com with your own FQDN.
