    Restricting Users


    Hi,
    I would like to know the way to restrict only the users from a particular
    country to visit my page using java. For example, if I want to make my site
    visible/accessible only to users from china, how to do this..

    Any help would be appreciated..

    thx..

    You can't tell what country your users are coming from.

    Actually, you can determine what country someone is connecting to you from.
    Every IP address on the net must be registered to a company (or individual).
    The registration process requires that you register the address (including
    the country) that the IP address are going to.

    Doing a lookup on the ip address of the individual who is connecting to your
    site is not impossible. Looking up the owner of the IP address will let
    you know the "network" that that user is connecting to you from.

    A number of software companies have had to use this method to dissallow downloading
    128-bit encrypting software (before the government allowed the export of
    128-bit software, of course).

    Now... doing this is another story.

    Although it can be done, it would require some code to do it. I have not
    had a need to write something like that, but if I ever do, I will share that
    code with you!

    Good Luck!
    Kevin

    Following from Kevin maybe rather than do a dynamic lookup an option could
    be to collate the IP information first, into a database.
    If the users IP address is in your database then allow them in.

    Your problem then is storing and regularly updating the data. You only
    need to store the IP address and its numeric so could be compressed and
    be used as the primary key to save space and for speedy access but the
    database would still be huge.
    Doing this you shift the issue from getting dynamic third party IP information
    to a standard everyday database sizing and update problem (which maybe more
    easier for you to solve depending on your circumstances).

    *

    Another, thought, you could narrow the users down by using timezone differences
    to only allow users in that access from your selected timezone/timezones.
    Not very secure though!

    *

    You could setup a registration process via email, so that you have a
    little more time to check them out before you approve their access.
