Function LoadFromUrl() Professional
Loads a document from a Web server.
The function is deprecated. Use the HttpClient() class instead.
Example: cResult := HttpClient():new( "http://www.alaska-software.com" ):send()
LoadFromUrl( <cURL> , ; [<nPortNumber>], ; [<nProtocol>] , ; [<cProxyUrl>] , ; [<acByPass> ] , ; [<cMethod>] , ; [<cPostString>], ; [<cCookie>], ; [<cAcceptType>], ; [@<nStatus>], ; [<bcUserFunc>] ) --> cWebContent | NIL
|INTERNET_DEFAULT_HTTP_PORT||Used for the HTTP protocol (non-secure communication)|
|INTERNET_DEFAULT_HTTPS_PORT||Used for the HTTPS protocol (secure communication)|
|INTERNET_COMMUNICATION_PUBLIC *)||Selects the HTTP protocol (non-secure communication)|
|INTERNET_COMMUNICATION_SECURE||Selects the HTTPS protocol (secure communication)|
The function returns the contents of an URL as character string. If the TCP/IP connection fails, the return value is NIL.
This function is used to load the contents of an URL using the HTTP or HTTPS protocol. The latter provides for a secure data exchange between client and HTTP server since data transferred via TCP/IP connections is encrypted. Calling the function with <cURL> as the sole parameter is sufficient in most cases. Special situations, like routing a request via a proxy server or submitting a HTML form, are covered by the remaining parameters.
The return value NIL indicates a connection failure which can have several reasons: The URL does not exist, illegal parameters are passed, the HTTP server is offline or there is no TCP/IP connection at all. If there is no TCP/IP connection but the computer is configured for a dial-up connection via modem, the operating system will open the dial-up dialog to establish a connection.
