haproxy redirect location和redirect prefix

<pre name="code" class="html">redirect location <loc> [code <code>] <option> [{if | unless} <condition>]
redirect prefix   <pfx> [code <code>] <option> [{if | unless} <condition>]
redirect scheme   <sch> [code <code>] <option> [{if | unless} <condition>]
  Return an HTTP redirection if/unless a condition is matched
  May be used in sections :   defaults | frontend | listen | backend
                                 no    |    yes   |   yes  |   yes

  If/unless the condition is matched, the HTTP request will lead to a redirect
  response. If no condition is specified, the redirect applies unconditionally.

  如果/除非 条件被匹配,HTTP 请求会导致重定向响应。如果没有条件被指定, 重定向无条件应用

  Arguments :
    <loc>     With "redirect location", the exact value in <loc> is placed into
              the HTTP "Location" header. When used in an "http-request" rule,
              <loc> value follows the log-format rules and can include some
              dynamic values (see Custom Log Format in section 8.2.4).

			  使用重定向位置, 准确的值在<loc> 是被放入到HTTP"Location" header.

			  用于"http-request" rule,

			  <loc> 值 遵循 log-format rules 包含一些动态值

                 mode http
    acl being_scanned be_sess_rate gt 100
    redirect location /denied.html if being_scanned

	#用法三、当用户访问172.16.1.100时，重定向到http://www.afwing.com
acl  dstipaddr  hdr(Host) 172.16.1.100
redirect  location   http://www.afwing.com if  dstipaddr

     acl host_wx.cn  hdr(Host)  120.55.118.6
     redirect location  http://wechatTest.winfae.com/index.html if host_wx.cn

 访问  120.55.118.6 跳转到http://wechatTest.winfae.com/index.html

		  重定向到一个路径

    <pfx>     With "redirect prefix", the "Location" header is built from the
              concatenation of <pfx> and the complete URI path, including the
              query string, unless the "drop-query" option is specified (see
              below). As a special case, if <pfx> equals exactly "/", then
              nothing is inserted before the original URI. It allows one to
              redirect to the same URL (for instance, to insert a cookie). When
              used in an "http-request" rule, <pfx> value follows the log-format
              rules and can include some dynamic values (see Custom Log Format
              in section 8.2.4).

			  重定向前缀,the "Location" header是建立在<pfx> 相关的和完整的URI 路径，

			  包含查询的字符串,除非  "drop-query"选项被指定(参见下面)

			  作为一个特殊的例子, 如果 <pfx> 等于 /,那么什么业不会插入在原始的URI前。

			  它会允许重定向到相同的URL（比如,插入cookie).

			  当使用在 http-request 规则, <pfx> 遵循 log-format
              rules

			  和 包含一些动态值
			          acl short_dom hdr(Host) -i etiantian.org
                     redirect prefix http://php.etiantian.org code 301 if short_dom
                   目的：使访问http://etiantian.org 跳转到http://php.etiantian.org

          acl host_wx2.cn  hdr(Host) -i  wechatTest.winfae.com
         redirect prefix  http://wechatTest.winfae.com/index.html if host_wx2.cn

	原因 wechatTest.winfae.com 匹配到这个就重定向到http://wechatTest.winfae.com/index.html ,导致写了多个Index.html
