Please accept my apologies for popping up on the list with an immediate
question, and even more so if it turns out that I am being stupid, but
this one really does have me confused. I have read the manuals and
searched and searched, but can't seem to find any reference to anyone else
having the same problem, or any related bug reports.
I am using Apache 2.4.7 (full details below).
The machine has two network interfaces with separate IP addresses, and I
want to use a conditional statement in the conf file of the default
virtual host to handle traffic coming in via the two IP's differently
using SERVER_ADDR to identify them. What I expected to be the complicated
bit all works fine, but this construct:
<If "%{SERVER_ADDR} == '<ip address of 2nd interface>'">
.......
</If>
<Else>
.......
</Else>
results in this:
root@mymachine:apache2# ./bin/apachectl restart
AH00526: Syntax error on line 118 of
/usr/local/apache2/conf/extra/configfile.conf:
Cannot parse condition clause: Variable 'SERVER_ADDR' does not exist
root@mymachine:apache2#
I have created a page where SSI tells me all the environment variables,
and SERVER_ADDR is there alright, a full list is below.
If, in my conf file, I change SERVER_ADDR to other variables including:
HTTP_HOST;
SERVER_NAME;
REMOTE_ADDR; and
SERVER_PORT,
apache restarts fine and conditional behaviour is as expected in those
instances. It just seems to be SERVER_ADDR which isn't working. In a
desperate attempt to find out what was going on, I even put a:
SetEnv SERVER_ADDR <ip address>
higher up the file, but the same error still came back.
Am I missing something and/or does this work for other people?
Supplemental information about my system follows.
