In computer networking, a web proxy server is a web-based server appliance or program which acts as an intermediate for requests coming from clients wishing to access websites which offer those resources. The protocol by which these requests are transmitted and received is known as HTTP or Hypertext Transfer Protocol, which is used to communicate data between web servers and client websites. There are a number of proxy servers that act as a gateway to allow access through another network interface, and there are web proxy servers which are intended to hide the real IP address from clients. For example, a common website used for online banking and shopping would be a web proxy server and not a regular web server.
There are two different types of web proxy setup, and the way in which they accomplish this task varies. The first method is called a layer 2 multiproxy. With this setup, multiple internal servers act as transparent proxies to the real web server. The requests to this server are then divided between the internal machines using the well-known concept of Wide Area Networks (WANs). These requests are then sent on their way to the end-user requesting them.
A second type of web proxy setup is known as a cache. With this setup, the web proxy server fetches a copy of all web pages from remote web sites and then passes them on to the client processing them. This copy can be changed periodically based on the current settings by the client and will thus ensure the best experience to the end-user. There is also a variation of this method known as session restore, where the user has the ability to change or delete any web page that has been recently visited and thus bypassing the cache.
Both of these web proxy servers use the same procedure to associate the requested web page with the IP address. This process is called IP filtering. The way this works is that the proxy servers use the IP address of the client, and then modify the requested page before sending it back to the client. Therefore, by simply changing the IP address, the same web site or application may be visited without any drastic interruptions.
Web proxy is usually configured using either simple configuration procedures or more complex configuration scripts by the end-user. Simple configuration procedures involve configuration of the web proxy software via a web browser. For more complex requests involving multiple IP addresses or request headers, it is usually necessary to use an application like IPAP or IPAQ. These utilities make usage of a database to store required information and commands, which are then used by the proxy server to configure requests with the proper values.
In order to allow for the IP filtering and other details to be remembered by the client, we have yet another type of configuration that needs to be covered. This one involves the use of an IP log feature. This log contains IP addresses and ports of all HTTP requests, which will be sent to the web proxy server. By entering the different fields that must be passed to the web proxy, clients can easily check if the settings that they want are being passed to the server, or not.
There are also some free vpn’s services available on the internet. Unfortunately, most free VPNs are not secure web proxies. They usually contain advertisements, spyware and sometimes viruses. If you are interested in securing your privacy at all times, then it would be best for you to settle for paid web proxy providers. You can read reviews about how reliable and trustworthy these providers are at the website below.
Web proxy also involves a process of manual IP assignment to the server. The client web server will ask the client for the IP address of the client’s system and port number, and then it will assign the latter to the client’s machine. This process is called the configuration of the tables. It is very important to configure these settings because they will serve as authentication requirements between the client and server, should the client’s system goes down or gets infected.
