An HTTP header is a field of an HTTP request or response that passes additional context and metadata about the request and response. Service Virtualization sends the following headers in the service response:

• Content-Length.
• Content-Type – If the content type was selected for the template.
• Any additional header specified in global header files.
• Any header added using C API used in the Callback methods.

Note: Using the HTTP header setting, the user can send additional HTTP headers in the response for the service.

Note: Once the user clicks on the ADD button on filling up the details, it will be displayed on a table. If a user wants to change any details on an existing header, they need to select the header by clicking on the checkbox in the table and click on Update button.
