DZone Snippets: htaccess code

no www

jnunemaker () — Thu, 30 Nov 2006 07:00:28 GMT



RewriteCond %{HTTP_HOST} ^www\.domain\.com$ [NC]

RewriteRule ^(.*)$ http://domain.com/$1 [R=301,L]

Remove www from URLs.

This is important to implement for your search engine ranking. Google, for example, thinks www.domain.com is a different site from domain.com, and this can seriously impact where you rank in Google. There are other ways of doing this, but the below is the only one that doesn't spit back a 500 error on my server, for some reason.



RewriteEngine On 

RewriteCond %{HTTP_HOST} ^www.domain.com$ [NC]

RewriteRule ^(.*)$ http://domain.com/$1 [R=301,L]

slashdot protection

Replace aaa.bbb.ccc.ddd with your own IP (so you always get to your site).
Replace www.yourdomain.com with your actual domain.

Just don’t mess with the user_agent and query_string lines. Those ensure that the Coral servers themselves can retrieve your page when they need to.

RewriteEngine on

RewriteCond %{REMOTE_ADDR} !^aaa.bbb.ccc.ddd$

RewriteCond %{HTTP_USER_AGENT} !^CoralWebPrx

RewriteCond %{QUERY_STRING} !(^|&)coral-no-serve$

RewriteCond %{HTTP_REFERER} ^http://(www\.)?digg\.com [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?slashdot\.org [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?slashdot\.com [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?fark\.com [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?somethingawful\.com [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?kuro5hin\.org [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?engadget\.com [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?boingboing\.net [OR]

RewriteCond %{HTTP_REFERER} ^http://(www\.)?del\.icio\.us

RewriteRule ^(.*)$ http://www.yourdomain.com.nyud.net:8080$1 [R,L]

Banning bad bots

lordrich () — Tue, 18 Apr 2006 15:49:13 GMT

The following code is the contents of /banme/index.php. This file is linked to from my main website but invisible to web browsers and disallowed in robots.txt. Therefore, only bad bots will ever follow this link and when they do so they will get banned in .htaccess and their ip address will be emailed to webmaster@example.com.



$i = getenv('REMOTE_ADDR');

$handle = fopen("../.htaccess", "a");

fwrite($handle, "Deny from $i\n");

fclose($handle);

echo "You've just got $i banned from this domain.  You are a very bad person.";

mail("webmaster@example.com", "Banned IP", "Deny from $i");

?>

Apache htaccess authentication

mvidberg () — Fri, 17 Feb 2006 10:00:42 GMT

For setting up a quick protected directory, put this in .htaccess



AuthName "Some Admin Area"

AuthType Basic

AuthUserFile /home/someclient/public_html/admin/.htpasswd

require valid-user

And then create the .htpasswd file via
htpasswd -c .htpasswd someuser

Redirect port 80 to port 443 (ssl)

RewriteEngine On 

RewriteCond  %{SERVER_PORT} !^443$

RewriteRule ^(.*)$ https://www.domain.de/folder/$1 [L,R]

Parse HTML files as PHP

peter (Peter Cooperx) — Wed, 06 Jul 2005 04:00:01 GMT

Add this to your .htaccess file in Apache:

AddType application/x-httpd-php .html

301 example.com to www.example.com

Syam (Syam Kumar R.) — Sat, 23 Apr 2005 18:01:08 GMT

RewriteEngine On



RewriteCond %{HTTP_HOST} !^(.*)\.example\.com$ [NC]

RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]

Prevent yourself from getting Slashdotted

peter (Peter Cooperx) — Sun, 10 Apr 2005 10:43:23 GMT

Assuming you have mod_rewrite and AllowOverride activated, throw this in the .htaccess file for the directory you don't want to be Slashdotted:

RewriteEngine On

RewriteCond %{HTTP_REFERER} ^.*slashdot.*$

RewriteRule .* - [F]

This all assumes the editors actually check the links before posting the story, but this should reasonably mean no-one on Slashdot can link to you, even if it's a bit over the top.

Build blacklist .htaccess file modified

Added prefix and suffix to make it a complete rewrite.
