What Is Function of Proxy Server? Oh, how quickly I had forgotten about the Proxy Server. The fact that this server, like every other server, plays a very important role is frequently overlooked, despite the fact that it has a very important function. Yes, this role is not as flashy as a database server, mail server, or application server, and yes, this role does not require complicated software or high-end hardware; however, someone has to do the dirty job, and the job of the Proxy Server is to do just that.
Consequently, what is the function of this server? What exactly does it mean to refer to someone as a “proxy“?
Other computers will access web pages through the Proxy Server on your behalf. When another computer makes a request for a web page (you should remember Web Server), the page is retrieved by the server and then delivered to the computer that made the request by using the web server. This server acts as a kind of broker between the remote server and the requested server, ensuring that the two servers do not communicate with one another directly but instead do so via the proxy server.
The web pages that have been accessed are also stored in the server’s cache. In this manner, if one user accesses a page and then another user wants to access the same page, the proxy server will remember the previously accessed page and will deliver the content without sending a request to the web server. This will result in increased efficiency for the process.
In addition, the Proxy can help the firewall by filtering content that is coming into and going out of the network. This adds an extra layer of security between the local area network and the internet. This function, which gives administrators administrative control over the content that is transmitted in both directions through the proxy, is typically referred to as a “Content Filtering” Proxy. Schools, religious institutions, and other organizations that are regulated or have minors as members make use of it because they recognize the significance of content filtering for their respective institutions.
It is sometimes necessary for an IT administrator to configure access to the network for users who are located remotely. This kind of access may be granted to the organization’s FTP server, website, or any other online business. What are the Benefits of Using a Public Proxy Server?
As I mentioned in the tidbit I wrote about web servers, you should set up a DMZ in situations like this one (Demilitarized Zone). This is an area that is not protected by the Firewall. Consider it as though it were your front yard for a useful comparison. It is yours, and you are free to store things there if you like, but anything of value that you might want to keep there is already inside.
What exactly is the relationship between a proxy server and the demilitarized zone (DMZ)? As a further precaution against security breaches, a proxy server is typically set up inside of a demilitarized zone (DMZ). By installing proxy servers within the DMZ, internal requests made to the internet can be redirected to the proxy server instead of going directly to the internet. It makes it much simpler to keep an eye on what users are doing and to stop the flow of any data that might go against the policies of the company.
To summarize, the proxy server is an essential component of your network infrastructure, despite the fact that it is relatively unnoticed by end users. Its primary function is to act as a middleman between the user and the remote server, which is a feature that constitutes an additional layer of security. It acts as a bouncer in the DMZ, which is a feature that adds another layer of security to the network, and it can cache websites that are frequently accessed, which is a feature that lowers the amount of bandwidth needed to access the internet.Advertisement
