I. iPhone Terminal code:
(Synchronous request)

Post = [[nsstring alloc] initwithformat: @ "message = % @", @ "Hello, world."];
Nsdata * postdata = [Post datausingencoding: nsasciistringencoding allowlossyconversion: Yes];
Nsstring * postlength = [nsstring stringwithformat: @ "% d", [postdata length];
Nsmutableurlrequest * request = [[nsmutableurlrequest alloc] init] autorelease];
[Request seturl: [nsurl urlwithstring: @ "http: // 192.168.10.220: 18080/DATa/1.jsp"];
[Request sethttpmethod: @ "Post"];
[Request setvalue: postlength forhttpheaderfield: @ "Content-Length"];
[Request setvalue: @ "application/X-WWW-form-urlencoded" forhttpheaderfield: @ "Content-Type"];
[Request sethttpbody: postdata];
// [Nsurlconnection connectionwithrequest: Request delegate: Self];

// Synchronous Request Code
// Returndata is the data returned.
Nsdata * returndata = [nsurlconnection sendsynchronousrequest: Request returningrequest: Nil error: Nil];
[Post release];

Ii. Web server code
<%
String message = request. getparameter ("message ");
System. Out. println ("message =" + message );
