Old problem. Its not a bug its a security fix. Versions below 1.3.20 have a long slash path disclosure
bug. Patched versions show 403 forbidden errors.

This is known and not a bug.

This test was done in an Apache 1.3.22 with PHP/4.0.6
Installed in Windows 98 Second Edition:

When you make the next request, it takes you to the
index of the site, the main page, as if you hadn?t put
the bars. This request has 232 bars

http://127.0.0.1////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

OK

But if you make a request with 233 bars it shows you the
Forbidden messsage. Here is the request with 233 bars.

http://127.0.0.1/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

And the result:

Forbidden
You don't have permission to access 
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
 on this server.

*****
Making this test I also realised that Internet Explorer doesn?t let
you put an adress of more than 2047 characters in the URL bar
