curl::option CurlHandle,"HTTPPOST" [,"name1","value1",...,"nameN","valueN"]
Use this option to specify the post parameters to be sent to the server when retrieving the URL.
Note that this option was greatly changed and is not compatible with fomer versions.
The optional arguments name1, name2, ..., nameN specify the names of the post fields and value1, value2, ..., valueN spefify the values. This way you can specify simple text post parameters. If you want to specify more complex post parameters, like file upload, you have to use the option FORMADD.
Use the option without optional arguments to close the repetitive use of the option FORMADD. In other word: if you specify the POST arguments using the option FORMADD you also have to use the option HTTPPOST after the last FORMADD option invocation.
