SYMPTOMS
========
When browsing an Internet Information Server (IIS) Web site from Netscape
Navigator version 4.05, the following error message may occur:
  HTTP Error 400
  400 Bad Request
  Due to malformed syntax, the request could not be understood by the
  server. The client should not repeat the request without
  modifications.
CAUSE
=====
The Uniform Resource Locator (URL) that Navigator is attempting to open contains
a space.
WORKAROUND
==========
To work around this problem, do one of the following:
- On the server, rename the file that contains a space to another name that
  does not contain a space.
  -or-
- In the Navigator Location text box, substitute "%20" (without the quotation
  marks) for the space in the URL. The string "%20" is the URL encoding
  equivalent of a space character.
  For example, if the URL is
  http://example.microsoft.com/has space.htm
  instead use:
  http://example.microsoft.com/has%20space.htm
MORE INFORMATION
================
When you view directories in "directory browse" format (no default.htm in the
directory), the link at the top of the page called "[To Parent Directory]" is
not URL-encoded with a %20 in place of any space-character in the filename.
When you use Netscape Navigator version 4.05 and click the link, the Web server
stops responding and the error message occurs.
