A load balancing issue for heterogeneous web servers is de- scribed in this article. The review of algorithms and solutions is shown. The selected Internet service for on-line echocardiography training is presented. The independence of simultaneous requests for this server is proved. Results of experimental tests are presented3. Key words: load balancing, scalability, web server, minimum response time, throughput, on-line simulator 1 Introduction Modern web servers can handle millions of queries, although the performance of a single node is limited. Performance can be continuously increased, if the services are designed so that they can be scaled. The concept of scalability is closely related to load balancing. This technique has been used since the beginning of the first distributed systems, including rich client architecture. Most of the complex web systems use load balancing to improve performance, availability and security [1{4]. 2 Load Balancing in Cluster of web servers Clustering of web servers is a method of constructing scalable Internet services. The basic idea behind the construction of such a service is to set the relay server 3 This is the accepted version of: Piorkowski, A., Kempny, A., Hajduk, A., Strzelczyk, J.: Load Balancing for Heterogeneous Web Servers.

  • Introduction
    HTTP Request Smuggling in 2020 – New Variants, New Defenses and New Challenges Amit Klein SafeBreach Labs Introduction HTTP Request Smuggling (AKA HTTP Desyncing) is an attack technique that exploits different interpretations of a stream of non-standard HTTP requests among various HTTP devices between the client (attacker) and the server (including the server itself). Specifically, the attacker manipulates the way various HTTP devices split the stream into individual HTTP requests. By doing this, the attacker can “smuggle” a malicious HTTP request through an HTTP device to the server abusing the discrepancy in the interpretation of the stream of requests and desyncing between the server’s view of the HTTP request (and response) stream and the intermediary HTTP device’s view of these streams. In this way, for example, the malicious HTTP request can be "smuggled" as a part of the previous HTTP request. HTTP Request Smuggling was invented in 2005, and recently, additional research cropped up. This research field is still not fully explored, especially when considering open source defense systems such as mod_security’s community rule-set (CRS). These HTTP Request Smuggling defenses are rudimentary and not always effective. My Contribution My contribution is three-fold. I explore new attacks and defense mechanisms, and I provide some “challenges”. 1. New attacks: I provide some new HTTP Request Smuggling variants and show how they work against various proxy-server (or proxy-proxy) combinations. I also found a bypass for mod_security CRS (assuming HTTP Request Smuggling is possible without it). An attack demonstration script implementing my payloads is available in SafeBreach Labs’ GitHub repository (https://github.com/SafeBreach-Labs/HRS).

  • Genesys Knowledge Center Deployment Guide
    Genesys Knowledge Center Deployment Guide Load-Balancing Configuration 10/2/2021 Load-Balancing Configuration Load-Balancing Configuration Deploying a Cluster Important Whenever you deploy a Knowledge Center Server instance, you must configure a Knowledge Center Cluster, even if you only plan on having one server. Knowledge Center Cluster stores all of the settings and data that are shared by each of the Knowledge Center Server instances that reside within it. This makes it pretty easy to add additional servers as your knowledge needs grow. Knowledge Center Cluster also serves as the entry point to all client requests sent to Knowledge Center Servers. The cluster application in Genesys Administrator needs to be configured to point to the host and port of the load balancer that will distribute these requests among your Knowledge Center Servers. Important If you only have one server deployed in your cluster, you can configure the cluster application to point directly to the host and port of that server. Configuring Your Load-Balancer Solution Let's take a look at how you might configure your load balancer to distribute requests between servers. This sample uses an Apache load balancer. Important Genesys recommends that you use a round-robin approach to balancing for Knowledge Center Server. If want to use a cluster of Knowledge Center CMS instances you'll need to use a sticky session strategy for load-balancing in order to keep authorized user on the same node. Genesys Knowledge Center Deployment Guide 2 Load-Balancing Configuration Important If you need more information about load balancing in a Genesys environment, the Genesys Web Engagement Load Balancing page provides some useful background information.

  • Implementing Reverse Proxy Using Squid
    Implementing Reverse Proxy Using Squid Prepared By Visolve Squid Team | Introduction | What is Reverse Proxy Cache | About Squid | How Reverse Proxy Cache work | Configuring Squid as Reverse Proxy | Configuring Squid as Reverse Proxy for Multiple Domains | References | Conclusion | | About ViSolve.com | Introduction This document describes reverse proxies, and how they are used to improve Web server performance. Section 1 gives an introduction to reverse proxies, describing what they are and what they are used for. Section 2 compares reverse proxy caches with standard and transparent proxy caches, explaining the different functionality each provides. Section 3 illustrates how the reverse proxy actually caches the content and delivers it to the client. Section 4 describes how to configure Squid as a reverse proxy cache. What is Reverse Proxy Cache Reverse proxy cache, also known as Web Server Acceleration, is a method of reducing the load on a busy web server by using a web cache between the server and the internet. Another benefit that can be gained is improved security. It's one of many ways to improve scalability without increasing the complexity of maintenance too much. A good use of a reverse proxy is to ease the burden on a web server that provides both static and dynamic content. The static content can be cached on the reverse proxy while the web server will be freed up to better handle the dynamic content. By deploying Reverse Proxy Server alongside web servers, sites will: • Avoid the capital expense of purchasing additional web servers by increasing the capacity of existing servers. • Serve more requests for static content from web servers.

  • Using AD360 As a Reverse Proxy Server
    Using AD360 as a reverse proxy server www.manageengine.com/active-directory-360/ Table of Contents Document summary 1 What is a reverse proxy? 1 Configuring AD360 as a reverse proxy 2 Enabling a context-based reverse proxy 3 Enabling a port-based reverse proxy 4 Document summary ManageEngine AD360 is an integrated solution comprised of multiple products including ADManager Plus, ADAudit Plus, and ADSelfService Plus. The purpose of this document is to guide you through the process of using AD360 as a reverse proxy server for the products integrated with it. What is a reverse proxy? Before jumping into the configuration steps, let's talk about what a reverse proxy is. A reverse proxy is a server that’s used as a strategic point in the network. It enforces web application security by hiding the location and identity of a server when remote users access an application over the internet. The reverse proxy server receives requests from external clients and forwards them to the target web application servers, which are usually located inside the LAN and are not directly accessible from outside. It also receives the response from the servers and forwards it to the client. Throughout this whole process, the client assumes that the reverse proxy is the web application server. Figure 1. A reverse proxy setup 1 For example, let's say the reverse proxy server is installed in the DMZ, and the application server is in the LAN, as shown in the figure above. In this case, requests from clients (users) are received by the reverse proxy server in the DMZ.
