If by "the URL" you mean the one that was used to retrieve the page in 
the first place, then the answer is "not necessarily, and rarely". 
Generally you need to parse the FORM and use its "action" attribute as 
the URL, plus whatever form fields are required.  It might be just login 
and password, but the choice of names is form-specific and there may be 
other (even hidden) fields that are required.  Tools such as can help you with this.
