Cookies and IP Addresses
Hi all,
Can you help me with this?
I want to get the servers IP address and the IP address of the referrer. Is
there a reliable way to do this? When I used 'REMOTE_ADDR' I get different
values even when I go directly to my site and then call 'REMOTE_ADDR'. Does
anyone know why? I want to use the IP address to ensure that some of the
code is only called from my site or from a valid IP address. I want the IP
address and not the URL so I can convert it into Hex.
$ENV{'SERVER_NAME'};
$ENV{'HTTP_REFERER'};
$ENV{'REMOTE_ADDR'};
In the discussions on cookies does any one know why when I set a cookie and
restart some time later my cookies are lost when I do the following in
JavaScript
var cookieDate = new Date()
cookieDate.setTime(cookieDate.getTime() + 10 * 365 * 24 * 3600 * 1000);//Add
10 years
document.cookie = escape(MyCookie=XXX + ;expires= +
cookieDate.toGMTString() + ;domain=.UltraTextPro.biz);

Re: Cookies and IP Addresses
Hi,
not sure about the REMOTE_ADDR, I've never had any problems with it. To get
an IP from a URI try this:
use Socket;
$referral_address = $ENV{'HTTP_REFERER'};
$referral_address =~ m#^.*http://([^/]+)/.*$#;
$IP = inet_ntoa inet_aton $1;
If you want the IP address in hex, just use inet_aton.

Anyways, since you are just learning, your method is

Info about IO::Socket
Hi all, Please tell me where can I find more information about using the IO::Socket. module. I want to avoid using the LWP module, because it is not working as it should. Thank you.

I've solved a problem. But why?
Hi all,
I've tried to make a script that gets a remote html page using IO::Socket.
If I wanted to use (like in some example from books) GET $path HTTP/1.1,
the script didn't want to work.
But it works OK if I ask for HTTP/1.0.
The strange thing is that the header returned by the Apache Server running
in Windows 2k says that it is HTTP/1.1, even though I've asked for HTTP/1.0.
Of course, this is happening only if I rename the file as index.html.
If I let it as index.shtml, it doesn't work with any method.
It prints only the first 4 KB of the html file.
Can you tell me why is not working if I try with HTTP/1.1, and why is not
working with .shtml files?
Thanks.
Here is the script:
#!/perl/bin/perl -w
print Content-type: text/html\n\n;
use IO::Socket;
my $host = 127.0.0.1;
my $path = /test.html;
my $port = 80;
my $socket = IO::Socket::INET - new(PeerAddr = $host,
PeerPort = $port,
Proto = 'tcp',
Type = SOCK_STREAM,
Timeout = 5,
)
or die Cannot connect to the server.\n;
$socket-autoflush(1);
#print $socket GET $path HTTP/1.0\n,
#Host: $host\n\n;
print $socket GET /index.shtml\n\n;
my $sock = $socket;
while ($socket) {
print;

HTTP 1.1 requires a Host request header. See sec. 14.3 of RFC 2616.
http://www.w3.org/Protocols/rfc2616/rfc2616.txt
Also, persistent connections are the default. See sec. 8.1.
Use LWP. Don't reinvent the wheel.

mod PERL versus PERL
Hello, Can someone tell me the coding difference and syntax difference between PERL and mod PERL? I'm getting errors in a script where there shouldnt be any. I've recently switched hosts and my new host uses mod PERL Thanks, Roger -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Perl is a language. mod_perl is an Apache module that allows you to write Apache handlers in the Perl language. I'm getting errors in a script where there shouldnt be any. I've recently switched hosts and my new host uses mod PERL To run regular CGI scripts under mod_perl, they need to be handled by a mod_perl handler that emulates a CGI-like environment. The most common module for this is Apache::Registry. To run CGI scripts under Apache::Registry, you need to be aware of a few things. Your best bet is to read the porting section of the mod_perl guide at http://perl.apache.org/docs/1.0/guide/porting.html -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Detecting a server-side condition every 30 seconds
Hello all,
I've got a requirement to write a script that checks some condition on the
server, and to display one image if the condition is true, another if the
condition is false. But I want to update the image every time the condition
changes.
For now, I'm using a META REFRESH tag so that the CGI script is rerun every
30 seconds. But this is not a very good solution, as the whole web page
gets redrawn even when nothing has changed. I've also thought about using
frames, and having one frame that repeatedly refreshes while the rest of the
page stays static. Again, not a very elegant solution.
Is there some way (perhaps using JavaScript in conjunction with CGI) to
query the server periodically, and only update the image when the condition
changes?
Here's the relevant excerpt from my code:
#
$GoNogo = go;# or stop depending on server-side condition
print 'End of Header';
Content-type: text/html
html
head
titleMy title here/title
meta http-equiv=Content-Type content=text/html; charset=iso-8859-1
meta http-equiv=Refresh content=30
End of Header
# irrelevant code here
print End of Javascript;
script language=javascript type=text/javascript
function setStatus()
{
if ($GoNogo != go)
{
document.fgColor = #66;
document.TheImg.src=go.gif;
document.links[0].href=#;
}
else
{
document.fgColor = #006600;
document.TheImg.src=stop.gif;
document.links[0].href=$launchUrl;
}
}
// --
/script
/head
End of Javascript
# irrelevant code here
print 'End of Body';
body onLoad=setStatus()
Top of page here
center a href=#img name=TheImg /a /center
More body text here
/body
/html
End of Body

CGI simple but not working
Hi all,
I'm studying the Learning Perl Second Edition and I'm learning cgi now.
The book presents a sample cgi that doesn't produces the expected result as
the book says it would. In sumary, this script should generate an one field
form with a default value - mint. But what appears in the screen are the
strings inside the q() function.
Could someone test it and say to me if there is something wrong?
The following script was retired from the section 19.6 Form Generation.
#!/usr/bin/perl -w
# cgi-bin/ice_cream: program to answer *and generate* ice cream
# favorite flavor form (version 3)
use CGI qw(:standard);
my $favorite = param(flavor);
print header, start_html(Hello Ice Cream), h1(Hello Ice Cream);
if ($favorite) {
print q(Your favorite flavor is $favorite.);
} else {
print hr, start_form; # hr() emits html horizontal rule: HR
print q(Please select a flavor: , textfield(flavor,mint));
print end_form, hr;
}
I'm running Redhat 6.2 perl version 5.005_03 built for i386-linux
But i tested this script with RH7.2 v5.6.0 built for i386-linux and it
doesn't work too
Thanks for any help,
