Squid is a fully-featured HTTP/1.0 proxy which is almost (but not
quite - we're getting there!) HTTP/1.1 compliant. Squid offers a rich
access control, authorization and logging environment to develop web
proxy and content serving applications.

This is current stable release.
Importing squid-2.7.4 (2.7.STABLE4) package as www/squid27. This is current stable release of Squid. pkgsrc change: * Drop support for pkgsrc original log_mime_hdrs_list. If someone want to use it, please feedback it to upstream. Changes from squid 2.6. * Experimental support for HTTP/1.1, mainly targeted at reverse proxy installations. Not yet HTTP/1.1 compliant hoewever. * A number of performance improvements; including request/reply parser, eliminating various redundant data copies and some completely rewritten sections. * Support for WAIS has been removed. * "act-as-origin" option for http_port - Squid can now emulate an origin server when acting as an accelerator. * "min-size" option for cache_dir - the minimum object size to store in a cache directory. Previously objects of any size up to a "max-size" maximum size would be considered as candidated for storing in a store_dir; this option allows the administrator to tune various stores for small and large objects rather than trying to tune it for both. * Support for Solaris /dev/poll for network IO - more efficient than poll() or select() and backwards compatible to Solaris 7. This must be manually enabled during configure by specifying "--enable-devpoll". * Support for FreeBSD accept filters. Use "accept_filter httpready" in squid.conf to enable this. * A semi-modular logging framework has been introduced, which both allows for more efficient non-blocking logging with the supplied logging daemon, but also allows for third-party modules to intercept the squid logs and process them. An example "UDP" logging helper, thanks to the Wikimedia Foundation, is included. * Support for rewriting URLs into canonical forms when storing and retrieving objects. A common practice seen in Content Delivery Networks is to serve the same content from a variety of different URLs or hosts; this makes efficient caching difficult. The store URL rewriting framework allows the administrator to rewrite a variety of URLs into one canonical form, so matching content from a variety of sources can be stored and retrieved as if they came from the same source, whilst still fetching the content from the original destination. See the "storeurl_rewrite_program" option for more information, and http://wiki.squid-cache.org/Features/StoreURLRewrite for some examples. * Object revalidation can now occur in the background. Cache validation can now occur in the background without requiring an active client to drive it. Stale content being revalidated can be served in situ whilst the object is being refreshed. See the "max_stale" and "refresh_pattern" options for more information. * introduce a new option, "zero_buffers", which controls whether Squid will zero the memory used for buffers and other data structures before use. This may or may not improve performance on specific workloads. * Cache authentication based on source IP address. This reduces the pressure on external authenticators which may not be able to keep up under high load - NTLM/winbind is a good example of this. See the "authenticate_ip_shortcircuit_access" and "authenticate_ip_shortcircuit_ttl" options for more information. * Support for configuration file includes has been added. "include" can now be used to include a configuration file or a glob of configuration files in a directory. * The default rules to not cache dynamic content from cgi-bin and query URLs have been altered. Previously, the "cache" ACL was used to mark requests as non-cachable - this is enforced even on dynamic content which returns cachability information. This has changed in Squid-2.7 to use the default refresh pattern. Dynamic content is now cached if it is marked as cachable. You should remove the default configuration lines with QUERY (acl, and cache) and replace them with the correct refresh_pattern entries. * Accelerator mode support cleaned up to behave more consistent when combining multiple accelerator mode options * Zero Penalty Hit support, allowing cache misses to be marked by custom TOS/priority values, useful when using packet shaping/prioritization outside Squid and needing to separate cache hits from misses. 2008-09-12 17:02:47 +02:00			`Squid is a fully-featured HTTP/1.0 proxy which is almost (but not`
