Path Rewrite Handler

This path uses the pattern matching of `PathMap` to rewrite URI's of received requests. A typical jetty.xml configuration would be:

         <Set name="handler">
           <New id="Handlers" class="org.mortbay.jetty.handler.RewriteHandler">
             <Set name="rewriteRequestURI">false</Set>
             <Set name="rewritePathInfo">false</Set>
             <Set name="originalPathAttribute">requestedPath</Set>
             <Call name="addRewriteRule"><Arg>/other/*</Arg><Arg>/test</Arg></Call>
             <Call name="addRewriteRule"><Arg>/test/*</Arg><Arg></Arg></Call>
             <Call name="addRewriteRule"><Arg>/*</Arg><Arg>/test</Arg></Call>
             <Set name="handler">
               <New id="Handlers" class="org.mortbay.jetty.handler.HandlerCollection">
                 <Set name="handlers">

                    </Item>
                  </Array>

Constructor Detail

### RewriteHandler

    public RewriteHandler()

Method Detail

### isRewriteRequestURI

    public boolean isRewriteRequestURI()

  Returns:
    the rewriteRequestURI If true, this handler will rewrite the value returned by `HttpServletRequest.getRequestURI()`.

### setRewriteRequestURI

    public void setRewriteRequestURI(boolean rewriteRequestURI)

  Parameters:
    `rewriteRequestURI` - true if this handler will rewrite the value returned by `HttpServletRequest.getRequestURI()`.

### isRewritePathInfo

    public boolean isRewritePathInfo()

  Returns:
    true if this handler will rewrite the value returned by `HttpServletRequest.getPathInfo()`.

### setRewritePathInfo

    public void setRewritePathInfo(boolean rewritePathInfo)

  Parameters:
    `rewritePathInfo` - true if this handler will rewrite the value returned by `HttpServletRequest.getPathInfo()`.

### getOriginalPathAttribute

    public String getOriginalPathAttribute()

  Returns:
    the originalPathAttribte. If non null, this string will be used as the attribute name to store the original request path.

### setOriginalPathAttribute

    public void setOriginalPathAttribute(String originalPathAttribte)

  Parameters:
    `originalPathAttribte` - If non null, this string will be used as the attribute name to store the original request path.

### getRewrite

    public PathMap getRewrite()

  Returns:
    A `PathMap` of the rewriting rules.

### setRewrite

    public void setRewrite(PathMap rewrite)

  Parameters:
    `rewrite` - A `PathMap` of the rewriting rules. Only prefix paths should be included.

### addRewriteRule

    public void addRewriteRule(String pattern,
                               String prefix)

  Add a path rewriting rule

  Parameters:
    `pattern` - The path pattern to match. The pattern must start with / and may use a trailing /* as a wildcard.
    `prefix` - The path prefix which will replace the matching part of the path.

### handle

    public void handle(String target,
                       HttpServletRequest request,
                       HttpServletResponse response,
