Subject [users@httpd] SERVER_PORT always reported at 80 (apache 2.2)
Date Tue, 04 Sep 2007 15:13:11 GMT
Hi all,

I'm running apache 2.2 on ubuntu 7.04 and I'm seeing come strange behaviour 
with the SERVER_PORT environment variable.

My server does not listen on port 80. My ports.conf contains :
Listen *:4242

and an nmap of my host shows only port 4242 listening. However, when I make a 
request to a cgi application, the SERVER_PORT env variable is set to 80. I've 
seen a few people with the same problem, but they were running 1.3 so the 
solution of having a Port directive does not work for me.

Here's the output of a session :

mikeh@chewbacca:/etc/apache2$ nmap localhost

Starting Nmap 4.20 ( ) at 2007-09-04 16:10 BST
Interesting ports on localhost (
4242/tcp   open  http

mikeh@chewbacca:/etc/apache2$ telnet localhost 4242
Connected to localhost.
Escape character is '^]'.
GET /cgi-bin/test.php HTTP/1.0

Content-type: text/html


content of test.php :

<?php echo $_ENV['SERVER_PORT']; ?>

I've tried this with perl and python to make sure it's not a php problem.

What am I missing?
