There are many services on the internet similar to TinyURL. These services can be simply described as "input a URL, simplify the URL". Apart from perhaps more advanced URL management systems, there's hardly any innovation among these websites.
However, dwarfURL is different. In addition to simplifying URLs, it also has a feature for managing URLs with passwords.
Additionally, dwarfURL is built using AJAX, making it more convenient to operate! Maybe you don't fully understand, so let me demonstrate it practically!
First, you can see that there are two input boxes on the homepage.
The first one is the familiar URL input area, and the second one is where you enter your password (this step can also be skipped). Then press the exciting button called "dwarfitbaby!" After that, you will receive your shortened URL!
