Help with apache reporting the wrong Port number

Hi All,

Sorry if this is a known issue, but I have searched Google/forums etc
and found no clear answer.

*The problem I have
*My Apache is accepting http traffic on port 81, but reporting it as
port 80 - via the PHP command:
$port=$_SERVER['SERVER_PORT']

I am doing it through a F5 Big-IP load balancer, and I think the problem
is either an apache config, or a big-ip config for how it sends the data
to apache.

*My Setup*
The Big-IP intercepts http traffic and forwards in on to port 80
it also intercepts https traffic on port 443, decrypts it and send it on
via http on port 81

My website then checks if it is on port 81, so I know traffic is secure.


*What I have tried*

If I put an iis (yuck) server behind the Big IP instead of apache and it
reports 80 and 81 correctly

If I put apache back behind the big-ip it reports both port 80 and port
81 as being port 80

If I stop apache running on port 80, and send data to port 81, it still
reports as port 80



Has anyone seen this before, or is it just something I've messed up some
place?

Many thanks

Gareth

Apache normally uses information supplied by the client to produce
self-referential URIs. See the following directives for details on how
to change that.

http://httpd.apache.org/docs/2.2/mod/core.html#usecanonicaln ame
http://httpd.apache.org/docs/2.2/mod/core.html#servername
http://httpd.apache.org/docs/2.2/mod/core.html#usecanonicalp hysicalport

Cheers

Tom

Thanks Tom,

Both for Speed and accuracy.

adding the following to my config did it:
UseCanonicalPhysicalPort On

You have saved me panic before the weekend (my project was due today and
I've been messing about with this all week).

Cheers

Gareth
