Chaning the server_software variable?

How would I be able to change the server_software variable for apache? I think that is what you call it, it contains data like: Apache/1.3.14 (Unix) mod_perl/1.24_01 PHP/4.0.4 mod_ssl/2.7.1 OpenSSL/0.9.6 .

Thanks in Advance.

But, how would I change it?
Like devshed's is: InfoWest.COM-CUSTOM-Apache/2.5.6
Thats not an Apache Default, with just minimal server tokens.
How did they do that? Something prior to compiling?

Start here -> http://httpd.apache.org/docs/mod/mod_env.html#setenv

Keep in mind, Context: server config, virtual host so you can't use .htaccess. server config is httpd.conf.

Sorry to bother you again, but the SetEnv didn't work. I wrote a quick perl script and printed the contents of two variables I defined in the httpd.conf file with SetEnv
one was SERVER_SOFTWARE and the other was SERVER_SOFTWARE2. SERVER_SOFTWARE2 worked correctly but the other didn't. For some reason Apache must be re-defining the variable again.

You can unset it first if that's the case.

http://httpd.apache.org/docs/mod/mod_env.html#unsetenv

It just doesn't want to work for me, this is what is in my httpd.conf:

UnsetEnv SERVER_SOFTWARE
SetEnv SERVER_SOFTWARE2 "This is var2"
SetEnv SERVER_SOFTWARE "This is var1"

SERVER_SOFTWARE2 gets passed to perl/cgi fine, but SERVER_SOFTWARE doesn't.
