How Do I Choose the Fastest Proxy Server?

The outbound proxy server (WY-CCProxy) is an important security function, and its work is mainly in the dialog layer of the Open System Interconnection (OSI) model, thus acting as a firewall. Outbound travel proxy servers are mostly used to connect to the Internet and the Internet. Domestic proxy server software is much simpler to set up than SYGATE, WINGATE, etc. This shared version supports up to 3 users. Support sharing Modem, ISDN, ADSL, DDN, dedicated line, etc. to access the internet. Supports HTTP proxy and FTP proxy protocols.

The same proxy server may have different speed effects in different regions or at different times. At the same time, some proxy servers appear occasionally once and will not appear again afterwards; some proxy servers are available for multiple consecutive days, but they will not reappear once they disappear; some proxy servers will reappear after disappearing for several days. If your proxy server is unavailable, please go to this site to find the latest and fastest proxy server. This site will often collect the available proxy servers and list them for your choice. If one doesn't work, try another one.

Function: It is to proxy network users to obtain network information. Visually, it is a relay station for network information.

In general, when we use a web browser to directly connect to other Internet sites to obtain network information, we directly contact the destination site server, and then the destination site server transmits the information back. The proxy server is another server between the client and the web server. With it, the browser does not go directly to the web server to retrieve the web page but sends a request to the proxy server. The signal is sent to the proxy server first. The proxy server retrieves the information needed by the browser and transmits it to your browser. Enter the address of the website you want to visit in the URL box. Clicking proxy browsing will open a new window linking the proxy server and wait for a few seconds. If an error such as the inability to link to the server appears at this time, please try to select another server above. Because the proxy server consumes a lot of resources and is time-sensitive, it sometimes fails to open, and you must try the proxy server multiple times. Automatically updates the latest available servers daily.

Most proxy servers have a buffer function, just like a large Cache, which has a large storage space. It continuously stores newly acquired data on its local storage. If the data requested by the browser is in its own The machine's memory already exists and is up-to-date, then it does not fetch data from the Web server again, but directly transmits the data on the memory to the user's browser, which can significantly improve browsing speed and efficiency.

More importantly: the proxy server is an important security function provided by the Internet link-level gateway (Gateway), and its work is mainly in the dialog layer of the Open System Interconnection (OSI) model, thus acting as a firewall.

For these reasons, proxy servers are mostly used to connect to the Internet and the Internet. In China, the so-called China Multimedia Public Information Network and Education Network are independent large-scale national-level local area networks and are isolated from the Internet. For various needs, some groups or individuals have opened proxy servers between the two networks. If we know the addresses of these proxy servers, we can use it to reach foreign websites.

HTTP Outbound proxy server HTTP

SOCKS Outbound proxy server SOCKS

SOCKS proxy is different from other types of proxy. It simply passes data packets and does not care what application protocol it is. It can be HTTP request, so SOCKS proxy server is much faster than other types of proxy server. The SOCKS proxy is divided into SOCKS4 and SOCKS5. The difference between the two is that the SOCKS4 proxy only supports the TCP protocol (that is, the Transmission Control Protocol), while the SOCKS5 proxy supports both the TCP protocol and the UDP protocol (that is, the user data packet protocol). Authentication mechanism, server-side domain name resolution, etc. SOCKS5 that can be achieved by SOCK4 can be obtained, but SOCKS5 that SOCKS5 can do is not necessarily. For example, our commonly used chat tool QQ requires a SOCKS5 proxy when using a proxy because it needs to use the UDP protocol to transmit data. .

VPN Outbound proxy server VPN

Refers to the technology of establishing a private network on a public network. It is called a virtual network mainly because the connection between any two nodes of the entire VPN network does not have the point-to-point physical links required for traditional private network construction. Instead, the architecture is provided by a public network service provider ISP. Logical platform on top of your network platform. User data is transmitted through logical tunnels (that is, point-to-point virtual private lines) established by the ISP in the public network (Internet). The corresponding encryption and authentication technology is used to ensure that the user's internal network data is safely transmitted on the public network, thereby truly realizing the exclusiveness of network data.
