Is Squid proxy server free?

What is the difference between squid proxy server and proxy server?

With that, I think it goes without saying that you are not allowed to run Squid in an unrestricted environment. In a word, what squid proxy server is the most powerful software in the world; but to use it in a controlled environment. Squid proxy server is not just a proxy cache server, but also is a Web accelerator, Content filter, URL filter, Anti-virus server, Proxy server, HTTP Server and a full load balancer for high end applications. Squid proxy server is developed by the National Laboratory for Applied Network Research at the University of California. In order to ensure a more stable performance, Squid proxy server also offers optional redundancy as well as high availability with automatic failover. The application can be deployed on Windows, Linux, OS/390 and many other platforms.

Squid squid proxy server proxy settings. I have been running squid proxy server on ubuntu 10.10 and it has been working fine for more than a month and now it stopped working without any information squid proxy server in /var/log/squid.log and /var/log/squid3/lastlog.

How should I check my squid proxy server and set it up. And also would I have to change any DNS settings as I have a VPS hosted in a datacenter?

What is the difference between HAProxy and squid proxy?

There is a good article about it.

Squid vs HAProxy: Which one should you use? The following table summarizes the main differences and similarities: The Squid proxy is more widely used than the HAProxy web accelerator; see this list of web servers that supports Squid. There are also more third-party modules for Squid than there are for HAProxy. Squid is used in the Linux kernel and as a general purpose cache server.

HAProxy is distributed as a software which is more portable. It is not only a web accelerator but can be used in many different roles, such as: HTTP proxy or transparent cache (like squid). HTTP accelerator for static content. Application proxy. Content cache (for the purpose of accelerating requests from multiple clients to a single backend). Squid and HAProxy are both very fast in their basic configuration. However, the Squid cache is capable of a much wider range of configuration, because its capabilities are more flexible than those of the HTTP accelerator.

Squid has advantages for applications requiring features beyond HTTP acceleration, such as access control, compression, URL rewriting, content caching, and SSL offloading. HAProxy has advantages for applications requiring a simple configuration, such as a simple load balancer, application proxy, and simple SSL offloading.
