Why is Tomcat a normalized URI?
This is for consistency with the behaviour of file systems as URIs are often translated to file system paths. As a result, the return value of HttpServletRequest#getContextPath () is expected to start with multiple / characters for some URIs. This will cause problems if this value is used directly with HttpServletResponse#sendRedirect () as redirect paths that start with // are treated as protocol relative redirects. To avoid potential issues, Tomcat will collapse multiple leading / characters at the start of the return value for HttpServletRequest#getContextPath () to a single /. This attribute has a default value of false which enables the collapsing of multiple / characters. To disable this behaviour, set this attribute to true.
