Apache 2.2.11 发布

Apache官方在今天放出产品系列2.2的最新版本2.2.11的源码包。按照惯例，大约几天后才会正式发布。您可以先用为快。
2.2系列的上一个版本是2008-10-07的2.2.10,这个版本主要就是修正了一些模块的bug.其他的产品线还是2008-01-17的1.3.41和2.0.63.看来1.3和2.0的开发更新已经放缓了。

Changes with Apache 2.2.11

  *) core: When the ap_http_header_filter processes an error bucket, cleanup
     the passed brigade before returning AP_FILTER_ERROR down the filter
     chain. This unambiguously ensures the same error bucket isn't revisited
     [Ruediger Pluem]

  *) core: Error responses set by filters were being coerced into 500 errors,
     sometimes appended to the original error response. Log entry of:
     'Handler for (null) returned invalid result code -3'
     [Eric Covener]

  *) configure: Don't reject libtool 2.x
     PR 44817 [Arfrever Frehtes Taifersar Arahesis <Arfrever.FTA gmail.com>]

  *) mod_autoindex: add configuration option to insert string
     in HTML HEAD (IndexHeadInsert). [Nick Kew]

  *) Add new LogFormat parameter, %k, which logs the number of
     keepalive requests on this connection for this request.
     PR 45762 [Dan Poirier <poirier pobox.com>, Jim Jagielski]

  *) Export and install the mod_rewrite.h header to ensure the optional
     rewrite_mapfunc_t and ap_register_rewrite_mapfunc functions are
     available to third party modules. [Graham Leggett]

  *) mod_cache: Convert age of cached object to seconds before comparing it to
     age supplied by the request when checking whether to send a Warning
     header for a stale response. PR 39713. [Owen Taylor <otaylor redhat.com>]

  *) Build: Correctly set SSL_LIBS during openssl detection if pkgconfig is
     not available. PR 46018 [Ruediger Pluem]

  *) mod_proxy_ajp: Do not fail if response data is sent before all request
     data is read. PR 45911 [Ruediger Pluem]

  *) mod_proxy_balancer: Add in forced recovery for balancer members if
     all are in error state. [Mladen Turk]

  *) mod_proxy: Prevent segmentation faults by correctly adjusting the
     lifetime of the buckets read from the proxy backend. PR 45792
     [Ruediger Pluem]

  *) mod_expires: Do not sets negative max-age / Expires header in the past.
     PR 39774 [Jim Jagielski]

  *) mod_info: Was displaying the wrong value for the KeepAliveTimeout
     value. [Jim Jagielski]

  *) mod_proxy_ajp: Fix wrongly formatted requests where client
     sets Content-Length header, but doesn't provide a body.
     Servlet container always expects that next packet is
     body whenever C-L is present in the headers. This can lead
     to wrong interpretation of the packets. In this case
     send the empty body packet, so container can deal with
     that. [Mladen Turk]

  *) core: Add ap_timeout_parameter_parse to public API. [Ruediger Pluem]

  *) mod_proxy: Add the possibility to set the worker parameters
     connectiontimeout and ping in milliseconds. [Ruediger Pluem]

  *) Worker MPM: Crosscheck that idle workers are still available before using
     them and thus preventing an overflow of the worker queue which causes
     a SegFault. PR 45605 [Denis Ustimenko <denusk gmail.com>]

  *) Windows: Always build the odbc dbd driver on windows, to be consistent
     with the apr-util default. [Tom Donovan]
