Hello everybody :)
A friend recently showed me an odd thing while playing with the command
wget under linux, I don't know why... But the result has surprised me :
$ wget http://www.prizee.com/parole.php
--02:35:29-- http://www.prizee.com/parole.php
=> `parole.php'
Resolution de www.prizee.com... 213.186.63.5
Connexion vers www.prizee.com|213.186.63.5|:80...connecte.
requete HTTP transmise, en attente de la reponse...302 Found
Emplacement: /index.php?joueur=1 [suivant]
--02:35:30-- http://www.prizee.com/index.php?joueur=1
=> `index.php?joueur=1.1'
Connexion vers www.prizee.com|213.186.63.5|:80...connecte.
requete HTTP transmise, en attente de la reponse...200 OK
Longueur: non specifie [text/html]
[ <=>
] 12,521
--.--K/s
02:35:30 (103.57 KB/s) - ? index.php?joueur=1.1 a sauvegarde [12521]
Then, he obtains an http error code (302) which redirect him on the
index page of the site.
With a browser like firefox, ie, safari we get the good page without
any redirection.
After that, I've made some tests. I tried to change the user agent
string with wget to identify it as mozilla, but I have the same result
(redirection). I tried links (command line browser) and curl but same
problem.
Here is the result of curl command :
$ curl -v http://www.prizee.com/parole.php
* About to connect() to www.prizee.com port 80
* Trying 213.186.63.5... connected

So, my question is : How we can detect the use of a command line tool
on a web site ? Like the site above. Thank you for your answers.
Sorry for my bad english, i'm french ;)
