Such as network sharing, network acceleration and network restriction breakthrough. HTTP agents are also often used for network application debugging, monitoring and analysis of network application programming interfaces called in Android / IOSAPP.

For the client, it is like the original server, and the client does not need any special settings. The client sends general requirements to the content in the reverse proxy namespace.

The reverse proxy then transfers the judgment request to the original server and returns the obtained content to the client.

What is the difference in purpose between a forward proxy and a reverse proxy? A typical use of a forward proxy is to provide a way for LAN clients in a firewall to access the Internet. Forward agents can also take advantage of buffering to reduce network utilization. A typical use of reverse proxies is to provide Internet users with servers behind firewalls.

Reverse proxies can also provide load balancing for multiple back-end servers or buffering services for slow back-end servers.

The forward agent allows the client to access any website through it and hides the client itself, so security measures must be taken to ensure that services are provided only to authorized clients. The reverse proxy is transparent and the visitor does not know that he is accessing the proxy.
