How-To Find Common Redirect Sources?

Answer

In some cases, you may see a redirect on your domain name that you are not sure of the source of. In some instances, you can find the source of this redirect via the headers of the site. This can be easily done via the cURL command over SSH. 

To  do this, please follow these steps: 

1. Log into your server via SSH

2. Run the following command.

   # curl -I yourdomainname.come

Once  the above command is ran, you will see output similar to the following: 

# [root@server ~]# curl -I yourdomain.com
HTTP/1.1 303 See Other

Server: Apache
X-Redirect-By: WordPress
Content-Language: en
Location: https://yourdomain.com
Content-Type: text/html; charset=UTF-8

In the above output, the important line contains X-Redirect-By. This is the source of the redirection if there is one found. Most common CMS's will use the X-Redirect-By header to indicate a source of a redirect. Some common CMS X-Redirect-By headers look as follows: 

• X-Redirect-By: WordPress
• X-Redirect-By: Joomla
• X-Redirect-By: Moodle
