Purpose of Proxy Servers
Following are the reasons to use proxy servers:
- Monitoring and Filtering

- Translation
- Accessing services anonymously
- Security
Monitoring and Filtering
Proxy servers allow us to do several kind of filtering such as:
- Content Filtering
- Filttering encrypted data
- Bypass filters
- Logging and eavasdropping
Improving performance
It fasten the service by process of retrieving content from the cache which was saved when previous request was made by the client.
Transalation
It helps to customize the source site for local users by excluding source content or substituting source content with original local content. In this the traffic from the global users is routed to the source website through Translation proxy.
Accessing services anonymously
In this the destination server receives the request from the anonymzing proxy server and thus does not receive information about the end user.
Security
Since the proxy server hides the identity of the user hence it protects from spam and the hacker attacks.
