Calling headers_out on a CGI object won't work...  You didn't say whether you're using CGI-style scripts (via ModPerl::Registry) or the mod_perl API, so I mentioned both variants.  In the latter case, you don't need CGI (nor CGI::Simple), i.e. you'd simply call headers_out on the object provided by Apache2::RequestRec.

    Hello almut,

    I totally applicate your time and effort in assisting me in this what I thought was a simple action.

    But I must be missing something and its looking right at me but I'm perl blind.

    So I have included the code I been using, please I know this is not the best approach on some things.

    The code is not complete, I stopped due to not able to drop a cookie to the client browser,
    after that I will check if cookie is valid and all that good stuff.
    package Apache2::CookieClient;
    use strict;
    use CGI::Carp qw/fatalsToBrowser/;
    use CGI::Cookie;
    use Crypt::CBC; # Calls MD5 from inside the package
    use DBI; # for SQL Server database connection
    use CGI qw(:standard);
    use Apache2::RequestRec (); # for $r->content_type
    use Apache2::Connection (); # for $c->remote_ip
    use Apache2::Const -compile => ':common';
    sub handler
    {
    my $r = shift;
    my $c = $r->connection();
    my $uri = $r->uri(); #incoming URL
    my $product = $r->dir_config('product'); #Var to grab product
    ## Cookie Vars.
    my $query = new CGI();
    my $your_host_name = $query->remote_host();
    my $new_cookie_product;
    my $retreived_cookie;
    my $encryption_key = $product; #You make up this phrase
    my $plaintext = $your_host_name . "::" . $product;
    my $retrieved_decrypted;
    my $cipher = new Crypt::CBC($encryption_key);
    my $retval = 0;
    my $skip_it = 0;


    ## When this cookie ever gets sent the browser
    $retreived_cookie = cookie('<companyname>' . $product); # Grabs the cookie

    ## No Cookie, need to check if they have IP access
    if (!$retreived_cookie) {
    if ( check_ip($c->remote_ip(), $product) )
    {
    $new_cookie_product = new_cookie($product,$plaintext,$cipher);
    ### I have tried everything I have seen/read and I can't make it add a cookie to client browser
    $r->headers_out->add('Set-Cookie' => $new_cookie_product);
    #Send them on there marry way
    return Apache2::Const::OK;
    }
    else # No IP matchs for that product, need to username login
    {
    #Send them to Login Page
    return Apache2::Const::OK;
    }
    }


    sub new_cookie {
    my($product, $plaintext,$cipher) = @_;
    my $ciphertext = $cipher->encrypt_hex($plaintext);
    return new CGI::Cookie(
    -name=>'<companyname>' . $product,
    -value=>$ciphertext,
    -path=>'/',
    -expires=>''
    );

    }


    sub check_ip
    {
    ##Check IP to Product code, query request to SQL SERVER to authenicate
    #returns a 0 = no access or a 1 = access granted
    my ($ip, $product) = @_;
    my $user;
    my $conn = DBI->connect("DBI:Sybase:<servername>", "<username>", "<password>") || die DBI->errstr;
    $conn->do("use <databasename>") || die DBI->errstr;
    my $qry = "exec <StoredProcedure>'" . $ip . "','" . $product . "'";
    my $smt = $conn->prepare($qry) || die DBI->errstr;
    $smt->execute() || die DBI->errstr;
    while(my $var = $smt->fetchrow_arrayref)
    {
    $user = $var->[0];
    }

    $smt = undef;
    $conn->disconnect;
    return $user;
    }
    }
    1;

      So is the 'Set-Cookie' header actually being sent, if you check with a tool like LiveHTTPHeaders?  In case it is, the problem lies elsewhere (e.g. cookies being disabled in the browser, etc.). Otherwise, if the problem turns out to be with your code / mod_perl / Apache (i.e. you don't see 'Set-Cookie' in the response headers), you could first try to play with a plain old CGI script (outside of mod_perl)...  in order to verify that cookies in general are working as expected.

      BTW, any specific reason to keep not using code tags, to format your nodes properly?  :)  It's really as simple as

      <c> ... your (verbatim) code here ... </c>

      It's not only easier than putting lots of <br /> as linefeeds and escaping stuff yourself, it also makes the code easier to read because indentation is being preserved.
