There are so many ways to do a "User-Agent spoofing".

Here i will give a two different ways to do that, but
firstly, what the hell is USER-AGENT?

USER-AGENT is a string that identifying a client by the host,
it can be a HTTP Client (FF/IE) it can be a FTP client (Like
SmartFTP, CuteFTP and etc), and it can be some IRC Client,
USER-AGENT its like the ID of the client.

USER-AGENT include the name of the client, it can include the
version, it can include the system that running under this
application and it can include other things.

Why we need this USER-AGENT string?
we not need that, but the host (the server) need that to know
how to refer to us, it can be like how the server arrange his
HTML TAGS that differents HTTP-clients can analyze and view
the chosen page.

For Example, take a look on this string:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.14)
Gecko/20080404 Firefox/2.0.0.14

Now, the server knows that we useing: 
Mozilla/5.0 (FF), under Windows NT 5.1 (XP)
en-US text standats, with Gecko/20080404 rendering engine 

and with this help he will know how to arrange his pages
and scripts that our client can understanding that perfectly.

Here you can see a list of the most user-agent that running
over the net: http://www.user-agents.org/index.shtml

We will make a "USER-AGENT" spoofing when we want to deceive 
to the server, when we want that he will think that we are a
different client.

The first way:
-Open your FF, and type: about:config
-right click>new>string
-type in the box:
"general.useragent.override"
-type the value that you want the your FF will use and save
it.

The second way:
If you must to use IE browser and you want to spoof it:
-Start>Run>Regedit
-then enter to:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
Internet Settings
-there look for the key "USER-AGENT" and change his value to
what ever you want, save it the leave the editor.


In both of this ways your client will path to the server the
string that you want and not the orginal string, its call a
"USER-AGENT SPOOFING".
