[fpc-devel] Fcl-Web 404 error

Fri Mar 11 14:37:41 CET 2011

Hi, does anyone knows how to return a correct 404 error from an fcl-web cgi app?.

I'm doing this:

procedure TFPWebModule1.myRequest(Sender: TObject;
  ARequest: TRequest; AResponse: TResponse; var Handled: boolean); 
begin
  AResponse.Code := 404;
  AResponse.CodeText := 'Not Found';     
  Handled := True;
end;

I use this because my Apache has an .htaccess's "ErrorDocument 404 ..." directive to take actions when 404 errors are found, but this is not working with my CGI. In my case, the contents (empty) sent by the CGI are shown in the client side, while I whould like to show the 404 message generated by Apache.

This is the response I'm getting from my cgi:

* About to connect() to 127.0.0.1 port 80 (#0)
*   Trying 127.0.0.1... connected
* Connected to 127.0.0.1 (127.0.0.1) port 80 (#0)

And this is a correct 404 error mesage:

* About to connect() to 127.0.0.1 port 80 (#0)
*   Trying 127.0.0.1... connected
* Connected to 127.0.0.1 (127.0.0.1) port 80 (#0)
