# RedactFromFile

You can use the `RedactFromFile` action to submit text in the `FileName` HTTP parameter, and return the input text with any matches that contain confidential or sensitive data redacted. Set `FileName` to the name of a file on the server machine that contains the input text to process.

## Example

    http://localhost:13000/?action=RedactFromFile&FileName=redaction.txt

This action might result in output similar to the following XML:

    <autnresponse>
    <action>REDACTROMTEXT</action>
    <response>SUCCESS</response>
    <responsedata>
    <autn:redacted_output>The driver [redacted] was questioned</autn:redacted_output>
    </responsedata>
    </autnresponse>
