If you want to increase the security level of your website, you can chuck these few lines of codes to prevent some common hacking techniques by detecting malicious URL patterns.
Apache
RewriteEngine On # proc/self/environ? no way! RewriteCond %{QUERY_STRING} proc/self/environ [OR] # Block out any script trying to set a mosConfig value through the URL RewriteCond %{QUERY_STRING} mosConfig_[a-zA-Z_]{1,21}(=|\%3D) [OR] # Block out any script trying to base64_encode crap to send via URL RewriteCond %{QUERY_STRING} base64_encode.*(.*) [OR] # Block out any script that includes a <script> tag in URL RewriteCond %{QUERY_STRING} (<|%3C).*script.*(>|%3E) [NC,OR] # Block out any script trying to set a PHP GLOBALS variable via URL RewriteCond %{QUERY_STRING} GLOBALS(=|[|\%[0-9A-Z]{0,2}) [OR] # Block out any script trying to modify a _REQUEST variable via URL RewriteCond %{QUERY_STRING} _REQUEST(=|[|\%[0-9A-Z]{0,2}) # Send all blocked request to homepage with 403 Forbidden error! RewriteRule ^(.*)$ index.php [F,L]
Comments will be moderated and
rel="nofollow"
will be added to all links. You can wrap your coding with[code][/code]
to make use of built-in syntax highlighter.I was wondering what the first line actually does? I'm familiar with the script blocking, that's is pretty obvious but what about:
On a side note, why rel=nofollow for comments when you dofollow all social networks? Why does facebook deserve all your pagerank juice over users who actually read your content and want to engage with you?
Thanks.
