<pre><code>currentElement = [[NSString alloc] init];
NSString* email=[NSString stringWithFormat:@"sbhushan@gmail.com"];
NSString* password=[NSString stringWithFormat:@"5Pb&amp;Q?4t"];
NSString* soapMesasge=[NSString stringWithFormat:
                       @"&lt;?xml version=\"1.0\" encoding=\"utf-8\"?&gt;"
                       "&lt;soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\"&gt;"
                       "&lt;soap:Body&gt;"
                       "&lt;Authentication xmlns=\"http://tempuri.org/\"&gt;"
                       "&lt;userId&gt;%@&lt;/userId&gt;"
                       "&lt;password&gt;%@&lt;/password&gt;"
                       "&lt;/Authentication&gt;"
                       "&lt;/soap:Body&gt;"
                       "&lt;/soap:Envelope&gt;",email,password];


NSURL* url=[NSURL URLWithString:@"http://codeexsolutions.com/HosService/ServiceHOSProvider.asmx"];
NSMutableURLRequest* theRequest=[NSMutableURLRequest requestWithURL:url];
NSString* msgLength=[NSString stringWithFormat:@"%d",[soapMesasge length]];

[theRequest addValue:@"text/xml" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue:@"http://tempuri.org/Authentication" forHTTPHeaderField:@"SOAPAction"];
[theRequest addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody:[soapMesasge dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection)
{
    webData =[[NSMutableData alloc]retain];
}
else
{
    // Inform the user that the connection failed.
