What should I send to PDF in order to end the HTTP submitting process?

[Antonyz]

Hi people. I made a PDF form with a submit button (url-encoded data with HTTP Post). But I did not use a common page such as php to receive it. The form data will be read by a 4D database client and it can receive all the fileds and values of the form correctely. However, although the data has been received by 4D, the submitting process is not yet finish. The progress bar is stuck at half waiting for the response. So what should I send to the PDF form to tell it that the transmission is succesful and finish this process? Thank you.

According to HTTP, you have to return some response. You can use an HTTP 204 "No content" type of response, which means that you are not returning anything, but it will complete things.
