Dynamic management of URL based on object-oriented paradigm

As the World Wide Web is popular, it is in high demand for retrieving the right information. In addition, the amount of information that is available has been increased. A search engine is used to locate information, due to the fact that searching for information from an increased amount of information is difficult. The search engine has started to use robot agents to facilitate easier access to the information. The paper proposes a dynamic URL management technique by using the object oriented paradigm for efficient performance of the robot agent. While URLs are saved in a file or database to decide whether the site is visited or not, this technique creates a URL object and pushes in a hash table. Therefore we can easily compare a new URL to others in a hash table which allows us to save, and insert a new URL if the URL is not in a hash table. This technique has the advantage of saving URL in a unique way. Other useful information about URL also can be stored. If the robot agent is suspended, we can save into files by using object serialization to save the main memory
