hello

I would like to know why my mod_security2 doesn't work with my apache config.

Here are my configuration :

I followed the instructions gived in the doc folder of the mod_security-2.5.7-win32.zip

I unzip file and put the mod_security2.so and libxml2.dll in a new folder named mod_security2 in the apache/modules/ directory.

I installed Install the Visual C++ 2008 Redistributable Package,

Then i added theses lines in the httpd.conf file :

LoadFile bin/libxml2.dll (i also put this file in th bin apache/bin directory)
LoadModule unique_id_module modules/mod_unique_id.so
LoadModule security2_module modules/mod_security2/mod_security2.so


in my httpd.con i write very simple directives like this
Code:

# Configuration for mod_security
<IfModule mod_security2.so>
 
# Turn the filtering engine On or Off
SecFilterEngine On

# Change Server: string
SecServerSignature "ca marche"


</IfModule>
# End of mod_security.

when i test my server name in the header is alway "apache" i'm waiting "ca marche"
my server is apache 2.2.8 and i use mod_security2.

when i watch in my log there are empty et in my apache error log i see
[notice] ModSecurity for Apache/2.5.7 (http://www.modsecurity.org/) configured.
i don't understand where is the mystake
thank

SecFilter* is pre version 2.5, or got changed in 2.5 along the way, do not remember. If one looks at the docs under the run time directives, there is no SecFilter anything anymore.

I'm looking at Steffen's readme and I do not see SecFilter

Should now be: SecRuleEngine On
All old SecFilter are now SecRule

I have at times had problems with one or both of these
SecRequestBodyAccess On
SecResponseBodyAccess On
