What are the types of Proxy Server?
There are various types of Proxy Server which are as follows −
Forward Proxy Server − A forward proxy is a type of proxy server that generally passes requests from users in an internal network to the internet through a firewall.
Forward proxies are configured to allow or deny the user's request to change through the firewall to create content on the Internet. If the proxy enable the user's request, it forwards it to the internet server through the firewall. The internet server sends its response to the proxy. The proxy sends this return back to the user.
Public proxy − Public proxies are accessible to anyone, and it works by supporting its users its IP address to protect their identity. This proxy cheap and simply accessible leaves its users more at risk of their information being breached.
Shared Proxy − A shared proxy server is used by higher than one user at a time. It supports an IP address to the user that can be shared with multiple clients. It also enables users to choose the location from where the user wants to search. It is conceptual for users who do not need to spend a lot of money on a quick connection. The advantage of shared proxy is low cost. The disadvantage of it is that a user can be get blamed for someone else's mischievous event.
Transparent proxy − Transparent proxies can be used to remain hidden from those that it is required on. This type of proxy is beneficial for organisations which need to implement a proxy without increasing the employee’s awareness that they are using one. Transparent proxies are more accessible to specific security threats including SYN flood denial of service attacks.
Distorting proxy − Distorting proxies change their IP address to protect their identity from the focus website. This is a best option for users who need to maintain their location hidden while using the internet.
Data Center Proxy − It is a specific type of proxy that is not associated with the ISP. It is supported by multiple corporations through a data center. These servers can be discovered in physical data centers. It is conceptual for clients who need fast responses. It does not support high-level anonymity. For this reason, it can establish client information at high risk.
HTTP Proxy − HTTP proxies are those proxy servers that are used to store cache documents of the browsed websites. It stores time and improves the speed because cached files occupy in the local memory. If the user need to access the similar file proxy itself supports the same file without browsing the pages.
