An HTTP proxy, or HTTP server, acts as an intermediary between a client browser and a destination web server, filtering and forwarding HTTP requests and responses. It can be used for various purposes, such as filtering or caching content, blocking certain types of content, bypassing firewalls, or changing the clients IP address. The HTTP proxy protocol routes client requests from web browsers to the internet and supports rapid data caching. It also provides security benefits by examining web traffic to identify and block suspicious activity, protecting web servers from external cyberattacks. Additionally, HTTP proxies can be used to bypass target website restrictions, making them particularly relevant for web scraping and web crawling.
When a client makes an HTTP request, it sends the request to the proxy server, which then forwards the request to the web server. The web server sends the response back to the proxy server, which in turn forwards the response back to the client. This process allows the proxy server to examine the request and decide whether to forward it to the intended server. There are different types of HTTP proxies, such as transparent proxies, which reveal the clients IP to the server, and anonymous proxies, which hide the clients IP address and other information.
In summary, an HTTP proxy is a crucial tool for companies of all sizes, providing better online anonymity, aiding with data collection, and offering various security and customization benefits.
