For years we blocked Baiduspider due to the fact their bots do not obey the robots.txt directive and can really hurt site performance when they unleash 100 bots on the site each pulling pages many times per second.
Last year, I unblocked Baiduspider's IP addresses, and now the problem is back.

cwd
Cwd(3pm) Perl Programmers Reference Guide Cwd(3pm)NAME
Cwd - get pathname of current working directory
SYNOPSIS
use Cwd;
my $dir = getcwd;
use Cwd 'abs_path';
my $abs_path = abs_path($file);
DESCRIPTION
This module provides functions for determining the pathname of the current working directory. It is recommended that getcwd (or another
*cwd() function) be used in all code to ensure portability.
By default, it exports the functions cwd(), getcwd(), fastcwd(), and fastgetcwd() (and, on Win32, getdcwd()) into the caller's namespace.
getcwd and friends
Each of these functions are called without arguments and return the absolute path of the current working directory.
getcwd
my $cwd = getcwd();
Returns the current working directory.
Exposes the POSIX function getcwd(3) or re-implements it if it's not available.
cwd
my $cwd = cwd();
The cwd() is the most natural form for the current architecture. For most systems it is identical to `pwd` (but without the trailing
line terminator).
fastcwd
my $cwd = fastcwd();
A more dangerous version of getcwd(), but potentially faster.
It might conceivably chdir() you out of a directory that it can't chdir() you back into. If fastcwd encounters a problem it will
return undef but will probably leave you in a different directory. For a measure of extra security, if everything appears to have
worked, the fastcwd() function will check that it leaves you in the same directory that it started in. If it has changed it will "die"
with the message "Unstable directory path, current directory changed unexpectedly". That should never happen.
fastgetcwd
my $cwd = fastgetcwd();
The fastgetcwd() function is provided as a synonym for cwd().
getdcwd
my $cwd = getdcwd();
my $cwd = getdcwd('C:');
The getdcwd() function is also provided on Win32 to get the current working directory on the specified drive, since Windows maintains a
separate current working directory for each drive. If no drive is specified then the current drive is assumed.
This function simply calls the Microsoft C library _getdcwd() function.
abs_path and friends
These functions are exported only on request. They each take a single argument and return the absolute pathname for it. If no argument is
given they'll use the current working directory.
abs_path
my $abs_path = abs_path($file);
Uses the same algorithm as getcwd(). Symbolic links and relative-path components ("." and "..") are resolved to return the canonical
pathname, just like realpath(3).
realpath
my $abs_path = realpath($file);
A synonym for abs_path().
fast_abs_path
my $abs_path = fast_abs_path($file);
A more dangerous, but potentially faster version of abs_path.
$ENV{PWD}
If you ask to override your chdir() built-in function,
use Cwd qw(chdir);
then your PWD environment variable will be kept up to date. Note that it will only be kept up to date if all packages which use chdir
import it from Cwd.
NOTES
o Since the path separators are different on some operating systems ('/' on Unix, ':' on MacPerl, etc...) we recommend you use the
File::Spec modules wherever portability is a concern.
o Actually, on Mac OS, the "getcwd()", "fastgetcwd()" and "fastcwd()" functions are all aliases for the "cwd()" function, which, on Mac
OS, calls `pwd`. Likewise, the "abs_path()" function is an alias for "fast_abs_path()".
