How to Implement a Cache Proxy Server With Best Practices in Network Security

Proxy servers are an essential component of internet security. They conceal your online activity from others who you would rather not have access to that information. A proxy server is a server that facilitates communication between your personal computer and the websites that you visit.

This makes it more difficult for cybercriminals to monitor your online activities and protects you from being the target of cyberstalking. Proxy servers are not foolproof, but they do prevent a significant number of typical dangers from materializing.

What Is a Cache Proxy Server?

A proxy server is computer software. It receives information from internet web pages and processes them. If no harm is found, it sends them to the real server. It acts as a security wall between your system and the web.

It also copies the original requests made by web pages and stores them locally. This helps if the subsequent request arrives from the same web page. Moreover, if the data is required for further processing, this local copy helps.

How to Choose a Reliable Proxy Server?

There is a massive bulge in the proxy market. More cybersecurity cases reveal more proxy servers arriving. This is also increasing many unethical methods of marketing. In all this, it’s difficult for a commoner to choose the best reliable FB proxy server by all ethical means.

So, it’s good to discuss choosing a reliable proxy first. Later I will tell you how to implement a cache proxy server. Though you must be mindful of many criteria, a few essentials are given below.

Data center pricing is one of the main hurdles that a proxy hunter finds on his way. Data centers are the spaces that your server takes. It’s a kind of storage where your data is stored online. The proxy servers cost you the price of that storage and the security they provide.

While choosing a proxy server, be conscious of the data center pricing and the quality of that proxy server. Various proxy servers have different convenient data center pricing according to the features that specific proxy server provides. 

While selecting the proper data center pricing, consider the following points:

  • Determine which kind of proxy server is best suited to your requirements
  • Determine the capacity of the IP pool 
  • Learn about the necessary functions. Make sure every feature you need is available
  • Assess the efficiency of the service. You can do this by pre-testing
  • Pay attention to the support for customers
  • Examine the tools for the management of proxies
  • Avoid shady services at your best

6 Easy Step-by-Step Guide to Implement a Cache Proxy Server

Here is the best practice to implement a cache proxy server. Give a thorough reading and follow step by step. You can change the object cache instance’s memory allocation, disc offload directory, and other settings through the management interface. 

Step 1:

Go to Servers > Server Types > WebSphere Proxy Servers > proxy server name > HTTP Proxy Server Settings > Proxy Cache Instance Configuration to set up a WebSphere proxy server. 

Follow these steps and do it again for any other nodes that use proxy servers.

Step 2:

Turn on cache replication, disc offload, and cache size by choosing the proxy cache store instance and turning on each configuration parameter. If you want to get rid of data from your hard drive, it’s best to do so in a separate partition.

Step 3:

The proxy server’s administration panel lets you turn on caching from the server itself. In the administration panel, go to Servers > Server Types > WebSphere proxy servers > proxy server name > HTTP proxy server settings. It will lead you to the proxy settings page.

Step 4:

Click the Enable caching button after choosing a cache instance from the list.

Step 5:

To cache dynamic content, go to the proxy server’s administration dashboard.
Select Servers > Server Types > WebSphere proxy servers > proxy server name > HTTP proxy server settings > Proxy settings and then check the box that says Cache dynamic content.

Step 6:

You must turn on servlet caching on the application server and set the cache criteria in a cachespec.xml file to make dynamic content cacheable and clear the cache. When an invalidation is sent, the application server cluster’s invalidation servlet will wait for connections to its cache to update the URL.

Dynamic content is data created in real-time by an application running on an application server. In the application’s cachespec.xml, dynamic content must be marked as edge cacheable for a proxy server to be able to store it.

In the cachespec.xml file, you can also find the cache ID, dependency identifiers for invalidation, and expiration times. The proxy server can read this data because it uses the ESI protocol.

If something unexpected happens to the application server, the cache of a dynamic page may be cleared. The ESI Invalidation Servlet in the file DynacacheEsi.ear tells both the application server and the proxy server about these invalidation events.

Suppose you want to use dynamic caching on your proxy server. In that case, you’ll need to install the DynacacheEsi.ear file that comes with the product with the application that makes the dynamic content.

When the proxy server’s caching is turned on, static caching is automatically turned on.

Static content is data available to the public on the World Wide Web. It has HTTP response headers (like EXPIRES and LAST MODIFIED TIME) that say how long the response can be stored in a cache.

Final Remarks

In the world of rising cybersecurity cases, it’s a must to have a cache proxy server in action. A proxy server acts as a firewall between your server and the web. It filters out all malicious software requests and keeps your server safe.

When choosing the best suitable proxy server, datacenter proxy pricing plays a crucial role. Check all the available proxy services and their prices. While selecting data center pricing, keep in mind all the required features.

After selecting a cache proxy server, follow the steps above to implement it in your network security. An adequately set and implemented proxy server [performs way better. If you need any clarification your way, reach out to the experts.
