Servet and JSP tag have different results from request.getRequestURI()

Question

I use Spring MVC for a web site. I need to access a JSP page with the following url

http://127.0.0.1/passwordReset

In the controller for this page, HttpServletRequest request.getRequestURI() produces the following:

/passwordReset

On the page, a custom JSP tag is included the following way:

<jsp:include page="/WEB-INF/views/myTag.jsp" />

This tag extends SimpleTagSupport. In the doTag method, I have the following code

    JspContext context = getJspContext();       
    PageContext pageContext = (PageContext) getJspContext();  
    HttpServletRequest request = (HttpServletRequest) pageContext.getRequest(); 
    System.out.println(request.getRequestURI());

and the output is

/WEB-INF/views/passwordReset.jsp

Why is there this difference? How can I get "/passwordReset" from the custom tag?
