Notes

  • To find out the runtime errors of this function, use ErrorOccurred and ErrorInfo.
  • If cookies have been implemented for the specified request (<httpRequest variable>.ManageCookie), they are updated in the <httpRequest variable>.Send variable after the call to httpRequest. Therefore, during the next call to <httpRequest variable>.Send with this request, the cookies will be taken into account.
  • Versions 21 and later
    From version 21, the redirections are automatically taken into account in the HTTP requests. To manually handle redirects in HTTP requests, it is necessary to use the IgnoreError property of the httpRequest type variable with the httpIgnoreRedirectionconstant.

Security error in a secure transaction

During a secure transaction, the request may fail due to security errors:
  • invalid certificate or certificate coming from an unknown company.
  • the site name specified in the certificate does not correspond to a server.
  • invalid or expired certificate date.
  • redirection to a non-secure server.
These errors are returned by ErrorInfo.
If one of these errors occurs, you can re-run the request while ignoring the errors. To do this, simply change the Property IgnoreError of type Variable to httpRequest:
Error returned by ErrorInfo
(with the errCode constant)
Value of the Property IgnoreError of the Variable of type httpRequest
(these values can be combined)
