How to send PostData request for NSMutableURLRequest

Question

I have URL which takes a parameter. In Firefox. I have download add-on and find the parameter for the request. I found PostData Tab on the httpFox add-on tool and I saw the parameter and value.

I created a string and added the parameter, and encoded that string value

NSString *parameterId = [NSString StringWithFormat:@"ac$2_sdrex_es34_4333f=Caa111"];

NSString EncodeID = [parameterId
  stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];

...and created the PostData,

PostData = [encodeID  dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

...and set the postLength,

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

...and set the http header values,

[request setValue:postLength forHttpHeaderField:@"Content-Length"];
[request setHTTPBody:postData];

and then make the connection,

connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];

But this results in the following error...

Error Domain = NSURLErrorDomain code= -1002 unsupported url

I have encoded the URL too.

Can anyone advise me how to resolve this issue?

This is what after creating the postData!

NSURL *url = [NSURL URLWithString:urlString];    
    theRequest = [[NSMutableURLRequest alloc]initWithURL:url];

    [theRequest setValue:@"win-eqjf1b1ep06:20000" forHTTPHeaderField:@"Host"];
    [theRequest setValue:@"Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10" forHTTPHeaderField:@"User-Agent"];
    [theRequest setValue:@"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8" forHTTPHeaderField:@"Accept"];
    [theRequest setValue:@"en-us,en;q=0.5" forHTTPHeaderField:@"Accept-Language"];
    [theRequest setValue:@"gzip,deflate" forHTTPHeaderField:@"Accept-Encoding"];
    [theRequest setValue:@"ISO-8859-1,utf-8;q=0.7,*;q=0.7" forHTTPHeaderField:@"Accept-Charset"];
    [theRequest setValue:@"115" forHTTPHeaderField:@"Keep-Alive"];
    [theRequest setValue:@"keep-alive" forHTTPHeaderField:@"Connection"];


    [theRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [theRequest setHTTPBody:postData];

@all Thanks in advance

Please also post the code you use to initialise the NSMutableURLRequest itself, thanks. — Snips, Aug 06 '12 at 08:46

NSMutableURLRequest only supports http://, https://, ftp://, or file://

Are you using some other protocol?
