You might need a web proxy for a number of reasons. One of the most common uses is to unblock websites and bypass geographical restrictions or censorship. By routing your internet requests through a web proxy, you can hide your IP address and access websites that may be restricted in your region. Additionally, a web proxy can also be used for security and privacy purposes. For example, it can help protect your identity by hiding your IP address from websites and online services that you access. A web proxy can also act as a filter, blocking unwanted or potentially harmful content. Caching is another important function of web proxies, as they can store frequently accessed content locally, reducing the load on the target server and speeding up access times for users. Overall, a web proxy can provide a range of benefits, including improved security, privacy, and access to restricted content.
