I have mostly completed the databases in MySQL that store users infomration including "userid" and "password" - I can query this info from the database to make sure that an individual actually logs in on the log in page, but how do I carry over this information into all subsequent html pages? i.e. hold the log in over several pages, does this have anything to do with temporary cache and if so how do I use it?

Currently, I am attempting to set a cookie - which will, I gather, be used to authenticate the user from page to page and will expire when the user closes his/her browswer, but I do not know what is happening currently with my script- no error messages but I cannot find the cookie the gets created... does this script save a cookie to the user's browser and if so how do I gather that info on a separate php page?

$mycookie = cookie(-name => 'rusteaselogin',
               -value => $rowdata[0]);
print header(-cookie => $cookie);

yes the cookie is sent to the browser and stored there
you may get it back with
my $q = new CGI;
my $c = $q->->cookie('rusteaselogin');

Sessions, cookies, variables and arrays, oh my!

I still have not been able to get my scripts to work.

a - create cookie with PERL
b - store cookie in browswer with PERL
c - redirect to new PHP webpage embedded within a CGI PERL script
d - use PHP to ascertain the contents of the cookie stored in "b" so as to act as a indication that user is logged in properly.

The Code:

if (($useridcheck =~ $rowdata[2]) && ($passwordcheck =~ $rowdata[3]))
$mycookie = cookie(-name => 'rusteaselogin',
-value => $rowdata[0]);
print header(-cookie => $cookie);

print "Content-type: text/html\n\n";
open (CGI, ">readcookie.php") || die ("File not created");
rename ("readcookie.php", "../readcookie.php");
print CGI << "HTML file";

      <link rel='stylesheet' rev='stylesheet' href='stylesheet.css' type='text/css'>
      <body bgcolor=#E9E7DA>
      <table width=650 border=0><tr><td>
if (!isset(\$_COOKIE['rusteaselogin'])) :
     echo "<br>". session_id();
     echo "there is no cookie";

close CGI;

> rename ("readcookie.php", "../readcookie.php");

why this?
simply do instead:

open (CGI, ">../readcookie.php") || die ("File not created");

also add at end:

close( CGI );
exit( 0 );

It seems that my web hosting service does not have the module installed on their UNIX boxes... has caused much frustration, not to mention confusion.
