This discrepancy suggests a higher likelihood of encountering duplicate proxies. For instance, Zenrows provided approximately 6,000 proxies in the US alone.

What is a proxy server?

A proxy server acts as an intermediary between your computer (or local network) and the internet. When you send a web request, it goes to the proxy server first, which then forwards the request to the web server. The response from the web server also goes through the proxy server to reach you. This process helps in hiding your IP address, filtering content, bypassing geographical restrictions, and enhancing security and privacy online.

What is a reverse proxy?

A reverse proxy sits in front of one or more web servers, intercepting requests from the internet before they reach the servers. It can serve several purposes: load balancing, where it distributes incoming requests to prevent any single server from becoming overloaded; SSL encryption, where it handles HTTPS requests on behalf of the web servers; caching content to improve load times; and providing additional security and anonymity for backend servers.

What is a proxy statement?

A proxy statement is a document that a publicly traded company is required to send to its shareholders, containing information about the matters to be discussed at an annual shareholder meeting, including elections for the board of directors, financial performance, and other company proposals. It is often accompanied by a proxy form, allowing shareholders to vote without being physically present at the meeting.

What is a proxy bid?

A proxy bid is a feature commonly used in online auctions that allows a bidder to set a maximum bid amount for an item. The auction system then automatically bids on behalf of the bidder, up to their maximum limit, in response to other bids. This ensures the bidder remains the highest bidder until their maximum amount is exceeded, without requiring them to manually monitor and update their bid.

What is an open proxy?

An open proxy is a proxy server that is accessible by any internet user. Generally, proxy servers are configured to only allow connections from certain networks or IP addresses. However, an open proxy accepts connections from any user on the internet, making it a tool for anonymity but also a potential risk for abuse, such as for sending spam or conducting unauthorized activities.

How to use a proxy?

To use a proxy, you typically need to configure your web browser or application with the proxy server's IP address and port number. This can usually be done in the settings or preferences menu of the browser or application. Some proxies may require authentication (username and password). Once configured, your web traffic will be routed through the proxy server. For specific instructions, refer to the documentation of your browser or application, as the process may vary.

What is HTTP proxy?

An HTTP proxy is a type of proxy server that is designed specifically to handle HTTP requests, which are the foundation of web browsing. It facilitates the process of retrieving data from the internet by forwarding web requests from clients and then returning the web server's response back to the clients. HTTP proxies can help improve web browsing speed through caching, provide additional privacy and security, and allow for web content filtering and bypassing geographical restrictions.
