I'm new to Salesforce API, I'm trying to update salesforce case record comments from my applications, when I went through the samples, I see that in few samples, Url property of the SforceService is being set before SforceService.login() is called, this property is later overridden by the value returned by LoginResult.ServerUrl. I'm just wondering the importance of doing so... is it good practice to set Url property before calling login method? if yes, where do I get this Url? should I grab from WSDL? what if this changes later? -Santhosh
