property ResponseText: String read;
Example

{ Example result: HTTP/1.1 200 OK }
end;
Usage
ResponseText returns the complete received HTTP status line, including protocol version, status code and reason phrase.
Additional Technical Info
ResponseText returns Indy's complete response status-line string as read from the connection, for example HTTP/1.1 200 OK. Despite the property name, it is not just OK or another reason phrase. ResponseCode is parsed from this same string.
Reason phrases are optional in modern HTTP and are not authoritative. Servers and intermediaries can supply empty, nonstandard, localised or attacker-controlled text. Use the integer code and endpoint contract for program decisions; use this full line only for bounded diagnostics after sanitising it for the destination log or message.
For informational responses Indy keeps reading until the terminal response, except that status 101 is terminal. Followed redirects and in-process authentication replace intermediate status lines, so the property normally describes the final response that produced the captured body.
Velox does not clear this Indy field before starting an attempt. If failure occurs after response-content clearing but before a new status line, Content is empty while this property can still contain the preceding line. If proxy/intercept/SSL object initialisation fails before that clear, the old body can remain too. A transport/parsing failure can leave either previous or newly read text depending on its timing.
