File upload support

With HTTP Client component you can easily upload files to a web server for processing by a CGI or servlet.
The HTTP Request component creates the request data to be sent to the server with the POST method:

clHttpRequest1.AddSubmitFile('c:\uploads\document.zip');
httpClient.Post('http://www.domain.com/upload.asp', clHttpRequest1, response);

stream := TFileStream.Create('c:\4upload\filename.ext', fmOpenRead);
try
httpClient.Put('http://www.domain.com/uploads/filename.ext', stream, response);
finally
stream.Free();
end;

Proxy server support

The HTTP Client fully supports proxy authentication. You can specify the proxy server, proxy user and password and the component will automatically perform the negotiation process and use the most secure authentication method.

HTTP Header management

The HTTP Client component gives you complete control over the headers being sent. You can easily define any HTTP request headers for submission to a WEB server or retrieve headers from a HTTP response.

httpClient.Request := clHttpRequest1;

httpClient.Request.Header.Range := 'bytes=1024-4096';
httpClient.Get('http://www.domain.com/downloads/install.zip', stream);

ShowMessage(httpClient.ResponseHeader.ContentType);
