One of the best things I love Apache web server is that it instantly enables you to share files and resources via plain web directory index listing without having to spend time making any fancy web pages to serve them.
However, there are times when you need to hide things out. To disable web directory listing, you need just a simple directive in .htaccess of that directory. Insert this line to disable apache files listing for this directory and all directories or folders underneath it: Continue Reading

Increase your page load times and save bandwidth with easy and really effective methods using apache htaccess directives. This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.
These HTTP headers are an instruction to the client about the document’s validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered expired and invalid, and a new copy must be obtained from the source.

Setting up the server
The “good news” is that we can’t control the browser. It either sends the Accept-encoding: gzip, deflate header or it doesn’t.
Our job is to configure the server so it returns zipped content if the browser can handle it, saving bandwidth for everyone (and giving us a happy user). Continue Reading

If you want to redirect all non-www requests to your site to the www version, all you need to do is add the following code to your .htaccess file:
in your .htaccess file
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
This will redirect any requests to http://my-domain.com to http://www.my-domain.com. There are several benefits from doing that:
* It will avoid duplicate content in Google
* It will avoid the possibility of split page rank and/or split link popularity (inbound links).
* It’s nicer, and more consistent.
Note that if your site has already been indexed by Google without the www, this might cause unwanted side effects, like lost of PR. I don’t think this would happen, or in any case it would be a temporary issue (we are doing a permanent redirect, 301, so Google should transfer all rankings to the www version). But anyway, use at your own risk!
Something nice about the code above is that you can use it for any website, since it doesn’t include the actual domain name.
Redirecting www to non-www
If you want to do the opposite, the code is very similar:
in your .htaccess file
RewriteEngine On
RewriteCond %{HTTP_HOST} !^my-domain\.com$ [NC]
RewriteRule ^(.*)$ http://my-domain.com/$1 [R=301,L]
In this case we are explicitly typing the domain name. I’m sure it’s possible to do it in a generic way, but I haven’t had the time to work one out and test it. So remember to change ‘my-domain’ with your domain name! Continue Reading

suppose you want /articles.php?cat=$1&art=$2 to become magazine/1/2
then you need these two rules:
#articles.php?cat=$1&art=$2
RewriteRule ^magazine/([^/]*)/([^/]*)$ /articles.php?cat=$1&art=$2&marker [L]
RewriteCond %{REQUEST_URI} /articles\.php [NC]
RewriteCond %{QUERY_STRING} ^cat=(.*)&art=(.*)
RewriteCond %{QUERY_STRING} !marker
RewriteRule (.*) http://mydomain/%1/%2? [R=301,L]
