![]() ![]() The relationship between these components is detailed in the figure below. ![]() We constructed a Docker image which uses the Tor network to expose both SOCKS and HTTP proxies. Since it operates at a lower level in the networking hierarchy, a SOCKS proxy is also faster and more flexible than an HTTP proxy. Since it’s secure (the name is an abbreviation for “SOCKet Secure”), a SOCKS proxy cannot understand the contents of requests or responses, so is unable to modify or filter them. Whereas as HTTP is an application layer protocol (at the top of the OSI Model), SOCKS is a lower level protocol in the session layer.Ī SOCKS proxy uses the SOCKS protocol. An HTTP proxy is also able to filter or modify the content of the requests and responses passing through it. As a result, an HTTP proxy is only able to handle HTTP and HTTPS requests. Any further interactions require new connections.Īn HTTP proxy uses the HTTP protocol for all interactions with the client and server. Once this interaction is over there is no persistent connection between the client and the server. This means that the client (often a browser) sends a request to a server. HTTP (HyperText Transfer Protocol) is the dominant protocol for information exchange on the internet. Requests and responses pass through the proxy. The client connects to the proxy and the proxy then connects to the server. When a request goes through a proxy server there is no direct connection between the client and the server. What is a Proxy Server?Ī proxy server acts as an intermediary between a client and a server. This post details the Medusa proxy docker image which uses Tor (The Onion Router) as a proxy. At Fathom Data we have a few projects which require us to send HTTP requests from an evolving selection of IP addresses. ![]()
