      hi ,

           today i am telling you the advantage and disadvantage of proxy servers. You can judge yourself as a security point of view.

                 So there is a lot of use of these anonymizer. Some are follows-

      1.We can hide our system IP.

          2.   We can access restricted sites.

          3.  We can bypass our system from administrator restrictions.

              There are also some misuses of these proxies-

         1.    Someone can send Froude mails to other.
