Let’s take a closer look at each of them.
- FTP proxies are used to upload files to a remote server using the FTP protocol. For this purpose FTP clients are used, the most popular ones are FileZilla, CuteFTP, Total Commander.

This type of connection is in demand by webmasters, seoshniki, programmers and other specialists who are engaged in maintenance of web sites.
- CGI proxies are regular websites that can be accessed through a browser string. This is the easiest to use type of proxy, as it does not require any settings. Usually such websites are free of charge, and for an additional fee, users are offered advanced functionality, such as increased connection speed or choice of the country where the server is located. With the help of CGI-proxy webmaster assesses the availability and display of websites from other cities and countries, and ordinary users get anonymous access to sites that are prohibited in their local network. The disadvantage of CGI-proxy is slow operation, difficulty in using authorization, instability of connection due to mass media.
- SMTP proxies are mail proxies. They are used to control e-mail sending. With their help, users of both paid mail services and free of charge (for example, gmail, yahoo) can filter spam, flood, choose servers to handle specific mail flows. SMTP-proxies are often used to set up the sending of emails through mail clients (Mozilla Thunderbird, Microsoft Outlook, etc.)
- POP3 and IMAP proxies are used to set up e-mail reception. They indicate to the incoming server where exactly to retrieve the incoming mail.
- HTTP and HTTPS are the most popular and popular proxies. They are used to get quick and anonymous access to forbidden websites, to mask IP-address, country of stay and other parameters. HTTP/HTTTPS proxies are widely used by online marketers, webmasters, search engine optimization specialists, and gamers.
- There are two types of Socks-Proxies: socks4 and socks5. They are an intermediate server that serves as an intermediary between the user’s device and the requested server. Socks-proxies allow you to get anonymous access to sites that are banned by the network screen. The advantage of socks-proxy compared to HTTP/HTTTPS is that they provide an opportunity to manage not only browser traffic, but also to transfer files via FTP.
