        ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:location_cookie_url];
        [request setDelegate:self];
        request.shouldRedirect = NO;
        [request startAsynchronous];   

- (void)requestFinished:(ASIHTTPRequest*)request
{
        if ([[[request responseHeaders] objectForKey:@"Set-Cookie"] hasPrefix:@"Preferences"])
        {

            ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:current_client_url];
            NSString*Strr = [NSString stringWithFormat:@"{\"IsMobile\": true, \"offerGuid\": \"%@\"}",[self.mProduct objectForKey:@"Guid"]];
           
            NSLog(@"%@",Strr);
           
            [request appendPostData:[Strr dataUsingEncoding:NSUTF8StringEncoding]];
            [request setDelegate:self];
            [request addRequestHeader:@"Content-Type" value:@"application/json; charset=utf-8"];
