- sending an HTTP form (HTTPSendForm) or an HTTP query.
| | HTTPRequest | Starts an HTTP request on a server. | | HTTPResetForm | Clears an HTTP form that is currently edited. | | HTTPSend | Sends an HTTP request and waits for the response from the HTTP server. | | HTTPSendForm | Sends an HTTP form. | | HTTPSimulateNetwork | Simulates a slow network by limiting the download and upload speed. | | HTTPTimeOut | Sets the timeout for WLanguage functions that use the HTTP protocol (HTTPRequest, SOAPExecute, DotNetExecute, J2EEExecute, etc.). | | InternetConnected | Defines whether an Internet connection is enabled on the current computer. In mobile, you can also be notified when the status of the Internet connection changes. | | OpenAPIToHTTP | Builds the HTTP request to call a function of an API. It can then be sent using HTTPSend. | | Proxy | Specifies whether the communication functions that use HTTP or HTTPS must go through a proxy to execute their requests. A proxy is used to share the access to Internet between the different network computers. | | RESTSend | Sends a REST request and waits for the server response. |
The following advanced types can be used with the HTTP functions:

Sample components (WINDEV): WD Trace Socket
[ + ] The purpose of this example is to trace everything that occurs on a communication via socket, on a specific address, on a specific port. This example allows you to understand the principle of dialog via socket between two applications. Therefore, in the applications that dialog via socket, even if no trace option as implemented by the developers, you will have he ability to view all the exchanges performed on the socket. This example also enables you to understand the operating mode of the network protocols based on the sockets: POP3, SMTP, FTP, HTTP, and so on. Note for the users who are experienced in network communication: This example does not allow you to trace the UDP packages (only the TCP communications can be traced).
