Apache DirectoryMatch for Intranet-Style Access
I needed to ensure that within a rather large directory structure any directory named ‘intranet’ was only accessible by internal IP addresses.

Printing Random Array Elements in PHP and Javascript
Non-dynamic tag cloud? <script language=”JavaScript” type=”text/javascript”> var mytags = new Array( “histories”,”names”, “land”,”lists”,”free” ); var randomseed=Math.floor(Math.random()*8) for(i=0;i<mytags.length;i++){ var randomnumber=Math.floor(Math.random()*141) randomnumber=randomnumber+40; if(randomnumber%randomseed!=0){ document.write(“<a style=’font-size:”+ randomnumber +”%;’>”+ mytags[i] + “</a> “); } } </script> <?php$input = array(“histories”,”names”, “land”,”lists”,”free”);$rand_keys = array_rand($input, 30);for($i;$i<30;$i++){$randomnumber=rand(40,181);echo “<a style=’font-size:”.$randomnumber.”%;’>”.$input[$rand_keys[$i]] . “</a>\n”;}?>
Apache LDAP Authentication to Active Directory
I was testing authentication against Active Directory (LDAP) using Apache 2. The following worked for me in a .htaccess file but only after adding: LDAPVerifyServerCert Off in the main httpd.conf file. I presume this is related to the server name in the SSL certificate on the Active Directory server. AuthBasicProvider ldapAuthzLDAPAuthoritative OffAuthLDAPURL ldaps://adserver.prefix.tld.co.uk:636/DC=prefix,DC=tld,DC=co,DC=uk?sAMAccountName?sub?(objectClass=user)AuthLDAPBindDN “CN=someuser,OU=some ou,OU=another… Read more »
