[users@httpd] IfModule *rewrite*
Hi,
I put the following lines into my apache.conf (outside, before a VHOST
definition):
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteLog /var/www/logs/rewrite.log
RewriteLogLevel 2
</IfModule>
(I also tried mod_rewrite and rewrite_module)
Unfortunatly it seems it does not work.
But if I define the same lines within a VHOST it *does* work.
Why? Anything obvious? And yes, the modules *are* loaded *before* the
first IfModule statement.
~$ lsb_release -irs
Ubuntu
10.04
~$ apache2 -v
Server version: Apache/2.2.14 (Ubuntu)
Server built: Nov 3 2011 03:30:19
~$
Thanks, Helmut

Also, when using vhosts, you'll need to set RewriteOptions inherit and RewriteEngine on in each
vhost you want to apply your rules to.

Thanks (to all), works now.

The logging in mod_rewrite is inherited from the base server config to
a virtualhost (which your test requests are mapped to) the same way as
rules and conditions, with RewriteOptions +Inherit specified only.

Sure, but I might miss the forest through the trees.

Read it again, also
https://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewritelog,
still unsure.

If I specify RewriteLog within the server context it does not write the
logfile. If I specify RewriteLog within the virtual host context, it
does. RewriteLog is the only option I change, I do not touch any other
options.

2, specified in both, the server and the vhost context.

I hope so. The vhost context is just ~20 lines below the server context.

Yes.

Sure. As mentioned before, when specifiying the (no doubt identical)
directive within the vhost it works like a charm.

> in your web server error log file?
No. But see above.
Server context:
RewriteEngine on
RewriteLog /var/www/logs/rewrite.log
RewriteLogLevel 2
Vhost context:
RewriteEngine on
#RewriteLog /var/www/logs/rewrite.log
RewriteLogLevel 2
$some_conditions_and_rules
=> Rewrite works, logging does not.
Server context:
RewriteEngine on
(#)RewriteLog /var/www/logs/rewrite.log
RewriteLogLevel 2
Vhost context:
RewriteEngine on
RewriteLog /var/www/logs/rewrite.log
RewriteLogLevel 2
$some_conditions_and_rules
=> Rewrite works, so does logging.
Also removed the "<IfModule mod_rewrite.c>" tags, no difference.

Did you read the documentation?
https://httpd.apache.org/docs/2.2/mod/mod_rewrite.html#rewriteengine
"Context: server config, virtual host"
"The directive should occur only once per server config."
"If the name does not begin with a slash ('|/|') then it is assumed to
be relative to the /Server Root/."
If you are using RewriteLog in the server context but are not seeing a
log file:
- What is the value you have for RewriteLogLevel? Note that it defaults
to 0, but that a value of 0 will disable all rewrite logging regardless
of whether the RewriteLog direcitve is set. To get rewrite logging, you
not only have to set the RewriteLog directive, you also have to set
RewriteLogLevel to something other than 0.
- Are you looking in the right place? (Does the log file name begin
with a slash?)
- Does Apache HTTP Server have permission to open and write the log file
in the place you have specified?
- Are there error messages about creating/opening the log file in your
web server error log file?

Do I also need to configure
RewriteLog
within the VHOST?! Is that also a "Rewrite configuration"?! Because
only setting
RewriteEngine On
does not write a logfile...

"rewrite configurations are not inherited by virtual hosts. This means
that you need to have a |RewriteEngine on| directive for each virtual
host in which you wish to use rewrite rules."
