The Intercept tab is used to display and modify HTTP and WebSockets messages that pass between your browser and web servers. The ability to monitor, intercept and modify all messages is a core part of Burp's user-driven workflow. In Burp Proxy's options, you can configure interception rules to determine exactly what HTTP requests and responses are stalled for interception (for example, in-scope items, items with specific file extensions, requests with parameters, etc.). You can also configure which WebSockets messages are intercepted.
When an intercepted message is being displayed, details of the destination server are shown at the top of the panel. For HTTP requests, you can manually edit the target server to which the request will be sent, by clicking on the server caption or the button next to it.
The panel also contains the following controls:
Note: You can also use hotkeys to forward or drop intercepted messages. By default, Ctrl+F is used to forward the current message. You can modify the default hotkeys in the hotkey options.
The main panel of the Intercept tab contains a message editor that shows the currently intercepted message, allowing you to analyze the message and perform numerous actions on it.
The editor context menu contains numerous useful items. In addition to the standard functions provided by the editor itself, the following actions are available for HTTP messages:

This release introduces a new scan check for second-order SQL injection vulnerabilities. In situations where Burp observes stored user input being returned in a response, Burp Scanner now performs its usual logic for detecting SQL injection, with payloads supplied at the input submission point, and evidence for a vulnerability detected at the input retrieval point.
