    This web page addresses and deals with the issues of internet sharing, or what is commonly called a proxy service.  This is
done to allow more than one person to use an internet service at a time.  But there are down-sides to this.  Speed, is there
any?  Usability, can each user properly get and read their email?  Can each user properly write and send out an email?  Does the sharing system, provide for the proper amount of network and internet security?  Are the users safe?  Are their minors who
use the network, and do they require protection from objectionable content?  Is there adequate virus, and trojan protection?

    These are just a few of the basic questions that get asked about a proxy service.  So, let's take them one at a time...

Q: Does the proxy have limitations?

A: What is a proxy service?
    As defined, a "prok-sie" service, is the ability of one computer, to provide the sharable resources of the internet, and make
available to others.  Now keep in mind, this can only be done over a network.  That is, the computers that will be sharing, must
be linked together.

A: Speed, is there any?
    Speed is a concern for most internet users of today.  Everyone wants faster, and faster.  Well, if you are on a proxy service
to access the internet, and email, this may in fact be a concern to you.  When it comes to moving data across the world via
internet, everything is relative.  Remember, that the size and amount of data you have will move at varying speeds depending
on the speed of your internet connection.  Smaller amounts of data, move more quickly, than lager amounts.  This is always
true, regardless of your connection speed.  The speed will vary even more, when you have more than one user on the internet
connection, such as a proxy.  Because, the connection is "Shared" by all of the users on the proxy service.

A: Usability, can each user properly get and read their email?
    Only, if the proxy is setup and configured properly.  Or, if the user has clear access to the internet, and can access their
mail over the net on a remote server.

A: Can each user properly write and send out an email?
    The same applies here, as above.

A: Does the sharing system, provide for the proper amount of network and internet security?
    Are you safe using the proxy?  This will depend largely on the quality and the security of the proxy service.  Also, the server
should be properly secured with a strong firewall.  Such as [ZoneLabs] ZoneAlarm Pro.

A: Are their minors who use the network, and do they require protection from objectionable content?
    If you have children, or teens who have access to, or can use the service, the answer is Yes.  You will need to provide a net
filter for those young ones to be safe.

A: Is there adequate virus, and trojan protection?
    If you have a good firewall, and a decent virus scanning program.  Yes.  The server and the client computers should
BOTH have access to these (Install them on all of the machines who have access).

A: How does the proxy work?
    Like the dial-up access to the internet itself, the proxy does this in the same way, but for the other computers on the
network, who are not directly connected to the internet.

A: Should I use a proxy?
    If you have a network, and your client computers need access to the internet, yes.  Otherwise no.

A: Does the proxy have limitations?
    This will depend on the proxy service you decide to use.  There are many very fine, and very powerful proxies.  Depending
on your access and security needs, this limitations of the one you choose will vary from proxy to proxy.
