Sorry i am new her, i have too many problems with the mod_securtiy2

After problems to load the extension i have a problem to "enable" the module. My configfile like this:

Code: [Select]

LoadModule security2_module modules/mod_security2.so

<IfModule mod_security2.c>

    # Turn the filtering engine On or Off
    SecFilterEngine On

   
</IfModule>
If i try to restart the Apache (x64) i became the error that the apache cant start (The request operation failed...).
If i remove al lines between the IfModule the server starts.
I use Windows Server 2008R2 Datacenter (x64) and Apache 2.4.9 (VC9), mod_security2 (2.7.6)

what make i wrong ?

can any one help me pleas ?

sorry for the late response,

What does the  error.log say about this? If there is nothing there, then what does the windows Event Log say about this?

I try the example filter of the file readme.1st.txt:

I become this error in the logfile:

My target is the URL http://www.xxxx.com/?abc=../../ views as to prevent, so as to increase the security

try this in httpd.conf

AcceptFilter http none
AcceptFilter https none
EnableSendfile off
EnableMMAP off

Odd, I do not see an invalid quoted pair here
SecRule REQBODY_PROCESSOR_ERROR "[email protected] 0" \
      "phase:2,id:'000001',t:none,log,deny,msg:'Failed to parse request body.',severity:2"

but just to be sure, add a blank space after the \ in the first line and see.
