about path elements

[rick collette]

Hi, ranchers:
I am not clear about path elements of an ServletRequest object: request_uri, context_path, servlet_path. What is their use? Could anyone comment on these? Thanks
I checked Specs trying to find javax.servlet.include.request_uri, but it's not there. Where to find the explanations of these attributes?

Just trying to bring up to the top, does no one really know about the above?

Most of the answer is in SRV.4.4. Assume, for example,

The web-app is mapped to /myapp

In the web-app, there's a servlet called FooServlet mapped to /foo

The browser requests http://www.myserver.com/myapp/foo/bar.html?param=value

In that case, FooServlet will be invoked with the following request attributes:

request.getContentPath() will return "/myapp"

request.getServletPath() will return "/foo"

request.getPathInfo() will return "/bar.html"

request.getQueryString() will return "param=value"

request.getParameter("param") will return "value"

request.getRequestURI() will return either "/myapp/foo/bar.html" or "http://www.myserver.com/myapp/foo/bar.html", depending on the precise format of the browser request.

See the spec quoted above for more details. Does this help?
