The latest addition to Guineu is SYS(8009). With this function you can send and receive data over the internet or intranet using the HTTP protocol.

Local lcWeb
lcWeb = Sys(8009,"GET","http://guineu.foxpert.com")
MessageBox( Left(m.lcWeb,500) )
lcWeb = Sys(8009,"POST","http://server/process.php","data")

You are not limited to transfer text data. For instance, you can have a web page that calls a Visual FoxPro COM server. The COM server could execute a query into a temporary DBF and then return the DBF file. In the same way you can transfer a DBF file to the server where server side scripts can process the content.

Instead of a VFP COM server you could also use a PHP script that accesses a MySql database.

If you want to pass on state information to a VFP application running on the web server, you can use SAVE MEMORY to save all current variables. On the backend you can use RESTORE MEMORY to load the variable set into memory. This is especially useful when the remote script executes a query and query parameters have been stored in local variables.
