Making all your .html files run a Perl script
A RECIPE FOR DYNAMIC WEBSITES WITH PERL
or how to turn all ".html" URLs in a directory into dynamic pages via CGI scripts.
1. Enable Overrides on a directory by directory basis.
You'll want something like the following in your file /etc/httpd/conf/httpd.conf
<Directory "/home/website/htdocs">
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs-2.0/mod/core.html#options
# for more information.
Options Indexes FollowSymLinks ExecCGI
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit
AllowOverride All
#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all
</Directory>
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs-2.0/mod/core.html#options

It's the AllowOverride All that's vital here.
2. Ensure that your Apache server supports modi_rewrite
This line must be present (and not commented out) in /etc/http/conf/httpd.conf
LoadModule rewrite_module modules/mod_rewrite.so
If you have had to change your configuration file at steps 1 or 2, remember to restart Apache so that it re-reads the config file!
3. Turn the RewriteEngine on as appropriate
In a file called .htacceess in the directories you want to forward:
RewriteEngine On
RewriteRule ^(.*)\.html /cgi-bin/summat.cgi?what=$1
RewriteRule ^(.*)\.html /cgi-bin/summat.cgi?what=$1
4. Provide the script to which you've targeted your pages
#!/usr/bin/perl
print "content-type: text/html\n\n";
print "I done REAL fab<br>";
($name,$value) = ($ENV{QUERY_STRING} =~ /(.*)=(.*)/);
print "You have called up page $value.html";
print "content-type: text/html\n\n";
print "I done REAL fab<br>";
($name,$value) = ($ENV{QUERY_STRING} =~ /(.*)=(.*)/);
print "You have called up page $value.html";
