javascript - How to Encrypt the URL

Question

I want to know how to encrypt the URL on Apache/PHP?

For example:

www.example.com/how-to-encrypt.html

to

www.example.com/DMQRzZWMDdGQtbndzBHNsawN0aXRsZQR0ZXN0AzcwMQR3b2UDMjQwMjEwNQ

This example also seen on yahoo as well like this link:

us.yahoo.com/_ylt=As6pPqj3t7OBn2LQbZCUU7abvZx4;_ylu=X3oDMTVocThw330824863

I want to know how to do like this, is it through JavaScript/PHP/Apache?

Answer 1

You're probably looking for Apache mod_rewrite together with PHP. That URL isn't (and wasn't meant to be) encrypted, it's probably just a key that redirects to a database on Yahoo! severs. See this article.
