    • getContextRelativePath

      static String getContextRelativePath(javax.servlet.http.HttpServletRequest request)
      Gets the context path relative path of the URI. Returns the path of the resource relative to the context path for a request's URI, or null if no path can be extracted.

      Also performs url decoding and normalization of the path.

    • normalizePath

      static String normalizePath(String path)
      Normalizes a path by unescaping all safe, percent encoded characters.

    • lenientDecode

      private static String lenientDecode(String string, Charset encoding, boolean decodePlus)
      Percent-decodes a US-ASCII string into a Unicode string. The specified encoding is used to determine what characters are represented by any consecutive sequences of the form "%XX". This is the lenient kind of decoding that will simply ignore and copy as-is any "%XX" sequence that is invalid (for example, "%HH").
      Parameters:
      string - a percent-encoded US-ASCII string
      encoding - a character encoding
      decodePlus - boolean to indicate whether to decode '+' as ' '
      Returns:
      a Unicode string
