Hi Nikola,
If you're talking about the situation where a pop-up box appears requesting
username and password, this is usually nothing to do with perl or any other
cgi script - try looking for some info on '.htaccess' ( I haven't got any
good links on that, off hand).
The situation where you are confronted with a page containing a form to fill
in is, however, run by a cgi-script (often perl). It will appear when the
user clicks on a link to restricted info. What the user has really done, in
this case, is click on a link to the cgi-script. It generates the login page
and checks the user:pass data against a list of valid values (usually kept
in a separate file). It then proceeds according to whatever it has been
programmed to do.
With this method you cannot protect static pages ( with .htaccess you can ).
Everything the browser displays during such a session is generated by the
cgi script. Often, to avoid having the user be confronted with the login
form at every click, the script sets a cookie when the user successfully
logs in and , at every click, checks for the cookie. If the cookie is
present, the script generates the page the user wants to see - otherwise it
generates the login form.
That's the basics of most of 'em.
Cheers,
Rob
