- 2. What actually is Proxy server?
- 3. Indirect text to other network. Proxy is hardware/software
- 4. Individuals, universities, companies use proxy Proxy acts as a gateway, catch server/firewall
- 5. Proxy share connection with others
- 6. Purpose of using proxies:- It improves performance:- (a) It act as a cache server (b) It controls bandwidth It helps in surfing anonymously:- (a) It helps in browsing WWW without any identification It helps in filtering request:- (a) It prevent access to some sites and protocol. (b) It helps in time division.
- 7. Improve performance:- Caching:- (a) It reduce latency. (b) It reduce network traffic. Bandwidth control:- (a) It is policy based bandwidth limit. (b) It deny by network type.
- 8. Caching helps in speeding up internet access.
- 9. Caches diminish the need for network bandwidth, typically by 35% or more, by reducing the traffic from browsers to content servers.

- 12. Caching Proxy A caching proxy server accelerates service requests by retrieving content saved from a previous request made by the same client or even other clients
- 13. Web proxy A proxy that focuses on World Wide Web traffic is called a "web proxy". The most common use of a web proxy is to serve as a web cache.
- 14. Content-filtering web proxy A content-filtering web proxy server provides administrative control over the content that may be relayed through the proxy. It is commonly used in both commercial and non-commercial organizations (especially schools) to ensure that Internet usage conforms to acceptable use policy
- 15. Anonymizing proxy An anonymous proxy server (sometimes called a web proxy) generally attempts to anonymize web surfing.
- 16. Intercepting proxy An intercepting proxy combines a proxy server with a gateway or router. Connections made by client browsers through the gateway are diverted to the proxy without client-side configuration.
- 18. Caching By keeping local copies of frequently accessed file the proxy can serve those files back to a requesting browser without going to the external site each time, this dramatically improves the performance seen by the end user
- 19. Only makes sense to implement this at the ISP rather than the small business level because of the number of pages available Because of dynamic content many pages are invalidated in the cache right away
- 20. Load balancing (Reverse Proxy) A proxy can be used in a reverse direction to balance the load amongst a set of identical servers (servers inside the firewall and users outside) Used especially with web dynamic content (.asp, .php,.cfm,.jsp)
- 21. Security benefits Hide internal clients from external network Blocking of dangerous URLs Filter dangerous content Eliminate need for transport layer routing between networks Single point of access, control and logging
