AllowEncodedSlashes Error

Hi,
I have RH AS 3 installed, its pretty old and has the following kernel: 2.4.9-e.3
I have apache2 installed on it and I have the http.conf file configured with the following Modules:

LoadModule jk_module modules/mod_jk.so
JkWorkersFile /usr/local/jakarta-tomcat/conf/jk/workers.properties
JkLogFile /usr/local/jakarta-tomcat/logs/mod_jk.log
JkLogLevel info
# Mount mappings
JkMount /* ajp13

At the very end I need to enable AllowEncodedSlashes so i set this to- On

Now when I start apache
/etc/rc.d/init.d/httpd -k start

I get the following error:
Invalid command 'AllowEncodedSlashes', perhaps mis-spelled or defined by a module not included in the server configuration

I think this may not be supported with this kernel can anyone out there confirm this or am i configuring apache totally wrong?

Thanks in Advance
Rodgeen
