GetRequestURI outputs wrong path

Question

I've written a servlet Counter that outputs a jpeg image. I setContentType to "image/jpeg". And it works nicely when I coded a IMG tab ie. <IMG src="servlet/Counter"> in my index.htm page from the root directory.
However I notice that the request.getRequestURI(); statement in my counter servlet now returns the path where the servlet is (ie servlet/Counter) rather than the html page that calls it (ie root/index.htm).
How can I rectify this to get the caller's URI rather than the servlet path ?.

There is nothing wrong with your servlet container.
When changed the servlet to output to contenttype txt/html and output the counter as html code; Using the SERVLET tag (vs the IMG tag), the method getRequestURI() returns the path I want (i.e html path).
It looks like

than the servlet path ?.Maybe you can give the page name as an argument for
the Counter servlet.
like: <img
src="servlet/Counter?page=root/index.html">
and the in servlet code call:
request.getParameter("page");
The whole purpose of implementing this is so that I don't have to specify the path. Any other ideas ?
