Squid is a high-performance caching proxy server that stores frequently accessed web content to improve network efficiency. It reduces bandwidth usage on busy networks by caching content locally. Squid communicates with peer caches using the Inter-Cache Protocol and can operate as a traditional proxy or front-end accelerator. Configuring Squid involves setting up TCP/IP on the server, editing squid.conf to change ports and define access rules, restarting Squid, and configuring clients to use the Squid server address.

![SQUID SERVER:
Squid is a high-performance HTTP and FTP caching proxy server. It is also known as a Web proxy
cache. It can make your network connections more efficient. As it stores data from frequently used
Web pages and files, it can often give your users the data they need without their systems having to
look to the Internet.
Studies on very busy networks suggest that a Squid server can reduce the size, or bandwidth, of
your Internet connection. That can lead to considerable savings for larger offices.
Squid uses the Inter-Cache Protocol (ICP) for transfers between participating peer and parent/child
cache servers. It can be used either as a traditional caching proxy or as a front-end accelerator for a
traditional Web server.
STEPS TO CONFIGURE SQUID PROXY SERVER :
1. Configure a TCP/IP for Squid Server :
[root@localhost /]# netconfig or system-config-network or setup
IP address: ________________

HTTP Request Smuggling
HTTP request smuggling occurs when HTTP requests pass through multiple entities that parse requests differently, allowing an attacker to smuggle a request to one entity without the other being aware. There are two main causes - using HTTP connection modifications like Keep-Alive and Pipeline, which allow multiple requests over a single connection, and message body transfer encodings like chunked encoding, which send content in chunks. An attacker can craft requests that one entity parses one way based on headers like Content-Length, while the other entity parses differently based on Transfer-Encoding, allowing a request to be smuggled through.

Caching Strategies
A common request sent from your web browser to a web server goes quite a long way and it can take a great deal of time until the data your browser can display are fetched back. I will talk about making this great deal of time significantly less great by caching things on different levels, starting with client-side caching for faster display and minimizing transferred data, storing results of already performed operations and computations and finishing with lowering the load of database servers by caching result sets. Cache expiration and invalidation is the hardest part so I will cover that too. Presentation will be focused mainly on PHP, but most of the principles are quite general work elsewhere too.

Squid is a commonly used open source web proxy caching server that improves performance by caching content and controlling bandwidth usage. It provides access logging and filtering capabilities. To install Squid, it is downloaded and configured on a Linux system. Access control lists (ACLs) are defined in the configuration file to restrict access based on source/destination IP addresses, domains, URLs, or time of day.
Squid Caching for Web Content Accerlation
Squid is an open source web proxy and cache server that provides content filtering, access control, and caching capabilities to improve network performance; it sits between clients and external servers to filter web traffic based on configured rules and restrictions set by the network administrator using regular expressions and access control lists. Squid can also integrate with authentication servers like ncsa_auth to require passwords for user access through the proxy.

[Devconf.cz][2017] Understanding OpenShift Security Context Constraints
The document discusses OpenShift security context constraints (SCCs) and how to configure them to allow running a WordPress container. It begins with an overview of SCCs and their purpose in OpenShift for controlling permissions for pods. It then describes issues running the WordPress container under the default "restricted" SCC due to permission errors. The document explores editing the "restricted" SCC and removing capabilities and user restrictions to address the errors. Alternatively, it notes the "anyuid" SCC can be used which is more permissive and standard for allowing the WordPress container to run successfully.

Ch 22: Web Hosting and Internet Servers
Web hosting involves providing space on a server for websites. Linux is commonly used for hosting due to its maintainability and performance. A web server software like Apache is installed to handle HTTP requests from browsers. URLs identify resources on the web using protocols like HTTP and FTP. CGI scripts allow dynamic content generation but pose security risks. Load balancing distributes server load across multiple systems. Choosing a server depends on factors like robustness, performance, updates, and cost. Apache is widely used and configurable using configuration files that control server parameters, resources, and access restrictions. Virtual interfaces allow a single server to host multiple websites. Caching and proxies can improve performance and security. Anonymous FTP allows public file downloads.

Scale Apache with Nginx
The need to scale is in high demand in an age where everything is moving to the cloud. Though the standard Apache configuration could handle a website with moderate traffic, the minute it gets slash dotted or twitted multiple times could spell an embarrassing crash landing! If you are the administrator of such a website then good luck finding another job! On the other hand you value high availability in the midst of popularity then read on. On this one day workshop, we will show you how to scale your website and webapps to scale to handle thousands of simultaneous sessions the right way. The topics covered will include:
- Setting up Apache and NGiNXM
- Setting up a sample LAMP web app
- Benchmarking Apache performance
- Fine tuning Apache to improve performance
- Fine tuning NGiNX to improve performance
- Discussion about code level improvements when developing custom webapps using PHP

- 1. SQUID SERVER: Squid is a high-performance HTTP and FTP caching proxy server. It is also known as a Web proxy cache. It can make your network connections more efficient. As it stores data from frequently used Web pages and files, it can often give your users the data they need without their systems having to look to the Internet. Studies on very busy networks suggest that a Squid server can reduce the size, or bandwidth, of your Internet connection. That can lead to considerable savings for larger offices. Squid uses the Inter-Cache Protocol (ICP) for transfers between participating peer and parent/child cache servers. It can be used either as a traditional caching proxy or as a front-end accelerator for a traditional Web server. STEPS TO CONFIGURE SQUID PROXY SERVER : 1. Configure a TCP/IP for Squid Server : [root@localhost /]# netconfig or system-config-network or setup IP address: ________________ Netmask: ___________ _____ Default gateway (IP): ___________ _____ Primary nameserver: ___________ _____
