Url Rewrite Filter 兑现伪静态

Url Rewrite Filter 实现伪静态

伪静态是相对真实静态来讲的.
通常我们为了更好的缓解服务器压力,和增强搜索引擎的友好面.都将文章内容生成静态页面.
但是有的朋友为了实时的显示一些信息.或者还想运用动态脚本解决一些问题.不能用静态的方式来展示网站内容.
但是这就损失了对搜索引擎的友好面.怎么样在两者之间找个中间方法呢,这就产生了伪静态技术.

Based on the popular and very useful mod_rewrite for apache, UrlRewriteFilter is a Java Web Filter for any J2EE compliant web application server (such as Resin, Orion or Tomcat), which allows you to rewrite URLs before they get to your code. It is a very powerful tool just like Apache's mod_rewrite.

???? Redirect one url
??????? <rule>
