You need to recreate the view using the new 'string'.

You posted it.

Assuming the URL you want is:  http://www.experts-exchange.com

CREATE OR REPLACE FORCE VIEW "user"."USERS" ("PROFILE_ID", "USER_NAME", "FIRST_NAME", "LAST_NAME", "LOCATION", "URL")
AS
  SELECT n_user_profile_id,
    c_user_name,
    c_first_name,
    c_last_name,
    LOCATION,

Just for Clarification:
View is a object that store sql commands, not the results, therefore you cannot update view.
However, view can be recreated n number of times without effecting actual data.
More important is that if for some reason view gets invalidated, it automatically recompile on next access.
Even though view contains query, you can update the base tables (Conditions applied).
If you have heard that view contains data, that view is called Materialized view.
