SERVIDORES PROXY. “Speed up your connection to the best proxy / cache for Web”.
Squid has the following features:
- Proxy and Cache HTTP, FTP, and other URL. Squid Proxy provides a service that supports requests HTTP, HTTPS and FTP to computers that need access to the Internet and in turn provides the caching functionality which specializes in locally stored pages viewed by users recently.
Thus, increases speed access to Web servers and FTP information that is outside the internal network. - Proxy for SSL. Squid also supports SSL (Secure Socket Layer ) which will also accelerate encrypted transactions, and can be configured with extensive access controls on user requests.
- Cache hierarchies. Squid can be a part of a hierarchy of caches. Several proxies are working together to serve the page requests. Whenever a browser requests pages to a single proxy, if it does not have the page cache makes requests to his brothers, that if neither do make them to your / s parent / s. .. These requests can be made by two protocols: HTTP and ICMP.
- ICP, HTCP, CARP, caché digests. Squid is the ICP protocol, HTCP, CARP and cache digests that are intended to give a proxy "ask" to other proxy cache if they have stored a particular resource.
- Caché transparency. Squid can be configured for use as a transparent proxy so that connections are routed into the proxy without client-side configuration, and usually without the client aware of his own existence. So default Squid uses port 3128 to execute requests, however you can specify that it does in any other available port or to do a number of ports available at a time.
- WCCP. From version 2.3 implements Squid WCCP (Web Cache Control Protocol). Allows you to intercept and redirect traffic to a router to one or more proxy cache, making connectivity control of them. It also allows one of the designated proxy cache can determine how to distribute the traffic redirected along the entire array of proxy cache.
- Access Control. It offers the possibility of access control rules. This allows you to set access policies centrally, simplifying network administration.
- HTTP Acceleration. When a user request to an object on the Internet, this is stored in the cache, if another user does request to the same object, and it has not undergone any change since the previous user accessed, Squid will show that is already in the cache rather than re-download from the Internet. This feature allows you to navigate quickly when the objects are already in the cache and also greatly optimizes bandwidth use.
- SNMP. Squid allows you to enable this SNMP protocol provides a simple network management, which allows you to monitor, analyze and report status information from a wide variety of machines, able to detect problems and provide status messages.
- DNS resolver cache. Squid is made also by the program dnsserver, which is responsible for finding domain names. When Squid is run, it produces a configurable number of processes dnsserver , and each does its own search in the DNS. This reduces the amount of time to wait for the cache this DNS lookup.
