squid2和squid3的区别

时间:2012-12-26 17:04来源:未知 作者:ken 点击:

squid3.0是对squid的代码用c++进行了重大的内部重建和改写。

实现了ICAP和ESI。从它的squid.conf配置文件里面能看出来很多上面说的特性,但是在squid2.6里面的一些特性在squid3.0版本不能用。

Squid 3.0 represents a major rewrite of Squid and has a number of new features.

The most important of these are:

 

  • Code converted to C++, with significant internal restructuring and rewrites.
  • ICAP implementation (RFC 3507 and www.icap-forum.org)
  • Edge Side Includes (ESI) implementation (www.esi.org)

Most user-facing changes are reflected in squid.conf 。


 

Some of the features found in Squid-2.6 is not available in Squid-3. Some have been dropped as they are not needed. Some have not yet been forward-ported to Squid-3 and may appear in a later release.

 

  • refresh_stale_hit option. Not yet ported.
  • ability to follow X-Forwarded-For. Not yet ported.
  • Full caching of Vary/ETag using If-None-Match. Only basic Vary cache supported. Not yet ported.
  • Mapping of server error messages. Not yet ported.
  • http_access2 access directive. Not yet ported.
  • Location header rewrites. Not yet ported.
  • wais_relay. Feature dropped as it's equivalent to cache_peer + cache_peer_access.
  • urlgroup. Not yet ported.
  • collapsed forwarding. Not yet ported.
  • stable Windows support. Irregularly maintained.
