Why do I need HTTP Tunneling?

HTTP Tunneling allows you to use the Internet despite having firewall restrictions such as blocking specific firewall ports to restrict specific protocol communication. HTTP tunneling helps you to overcome this firewall restriction by sending specific protocol communication through HTTP protocol.
The attacker may use this technique for the following reasons:

• It assures the attacker that no one will monitor him or her while browsing.
• It helps the attacker to bypass firewall restrictions.
• It ensures secure browsing.
• The attacker can hide his or her IP address from being trapped.
• It assures that it is highly impossible for others to identify attacker online.
