# Blocking Traffic to Specific Hosts

With Fiddler Everywhere, you can create a rule that automatically blocks traffic to any matched host by forcibly closing the ongoing HTTP connection.

## Creating a "Block Traffic to Specific Hosts" Rule

Create a "Block Traffic to Specific Hosts" rule by setting the following actions through the [Rules Builder](https://www.telerik.com/fiddler/fiddler-everywhere/documentation/modify-and-filter-traffic/modify-traffic-with-rules).

1. Create a matching condition that uses the "When **all these conditions** are met **any number of times**" pattern.
2. Match by a **URL** where the string value defines the targeted hosts. For example: a regular expression that matches hosts like **example.com** and **google.com**
3. Create a **Close Non Gracefully** action.

This sample Fiddler rule matches all sessions where the host is **example.com** or **google.com** and closes the connection.

> tip The blocking actions are not final and can be combined with other actions. [Learn more about final and non-final actions here.](https://www.telerik.com/fiddler/fiddler-everywhere/documentation/modify-and-filter-traffic/conditions-and-actions)

Once the rule is created, enable the **Rules** tab, toggle the rule switch, and start capturing traffic.
