20+ .htaccess Hacks Every Web Developer Should Know About

Apache's .htaccess(hypertext access) configuration file can be a very powerful tool in a web developer's toolkit if used properly. It can be found in the webroot of your server and can be easily edited using any text editor. In this article I'm going to show you 20 .htaccess hacks and how to use them.

Before I start with this article I'd like to start by saying that abusing the .htaccess file will hurt the performance of your website. The .htaccess file should only be used if you have no other way to achieve certain things.

Make sure to back up your current .htaccess file before applying any of the following hacks.

1. Prevent Hotlinking

DDNS - Dynamic Domain Name System | What is DDNS , DNS

DDNS - Dynamic Domain Name System

We Know All before sending anything to his mail server, he will read the database from the public server for the latest ip address of mail server and put it as destination address.. But twas a small problem, at times after fetching the latest public ip of mail server, ISP DHCP renews the IP lease of mail server, hence the message lost.

Again after some time I started thinking about a vpn connectivity from an office which doesn't have public address, so the idea of DDNS came,

Before explaining DDNS, I hope you all have a good idea about DNS, For those who dont know, DNS is the one to one mapping between name to ip address. But in DNS its will not get updated dynamically and it may take even more than 24 hrs to get updated in the root DNS servers. Here come DDNS.

The PING of Death and Other DoS Network Attacks

What is known as Denial-of-Service (DoS) Attacks.?? Do You Prevent it or Not.? This Question Is Very Difficult.!!

I’m very disappointed to admit that in our days this type of attack is one of the most common attacks found in the network community.

Learning about these types of network attacks — learning your enemy — will help you be prepared for the worst. Once you understand your enemy’s behavior and the different types of network threats we’ll move on to specific solutions and how to protect your network.

DoS Attacks - Denial-of-Service Attack

Denial of Service Attacks can take many forms. The most important ones are:

• SYN Flood
• UDP Flood
• ICMP Flood
• Land Attack
• Teardrop Attack
