#  Referrer URL Condition

 The Referrer URL Condition gives you the ability to display a box to visitors coming to your Joomla! Website from a specific website or a list of websites by using their domain names as an indicator.

## [Options](#options)

 In the table below you can see which options are available to setup the Referrer URL Condition.

 | Name | Description |
|---|---|
| Match | Set whether to match or not the set referrers. |
| Referrer URL | In this repeater field, you can type in your Referrer URLs or parts of them one by one separating them in new lines.     For example, you can type it like this:     https://www.joomla.org/blog    https://www.joomla.org/blog/joomla-4   Or even like this:     /blog    /blog/joomla-4   Or even a mix of them if you'd like but there's rarely a use case for typing them mixed. |

## [Use Case](#use-case)

 A very common use case for the Referrer URL Condition is when you want to show a box for a user who is coming from an affiliate site or a social network like Facebook. For instance, if the user is somehow coming to your Joomla! Website from Facebook then perhaps you'd like to let him know that you also have a Facebook Page for him to like.

## [Troubleshooting](#troubleshooting)

 The referrer discovery is not always 100% accurate. It relies on the *HTTP\_REFERER* variable which can be empty due to the following reasons.

- Some browsers limit access to not allow HTTP\_REFERER to be passed
- The user entered the site URL in browser address bar itself.
- The user visited the site by a browser-maintained bookmark.
- The user visited the site as first page in the window/tab.
- The user clicked a link in an external application.
- The user switched from a HTTPS URL to a HTTP URL.
- The user has security software installed (Antivirus/Firewall/Browser extension) which strips the referrer from all requests.
- The user is behind a proxy which strips the referrer from all requests.
- The user visited the site programmatically (like, [curl](http://php.net/manual/en/ref.curl.php)) without setting the referrer header.
