NAME
Net::Whois::Raw - Perl extension for unparsed raw whois information
SYNOPSIS
use Net::Whois::Raw;
$s = whois('perl.com');
$s = whois('funet.fi');
$s = whois('yahoo.co.uk');
$OMIT_MSG = 1; # This will attempt to strip several known copyright
messages and disclaimers sorted by servers.
Default is to give the whole response.
$OMIT_MSG = 2; # This will try some additional stripping rules
if none are known for the spcific server.
$CHECK_FAIL = 1; # This will return undef if the response matches
one of the known patterns for a failed search,
sorted by servers.
Default is to give the textual response.
$CHECK_FAIL = 2; # This will match against several more rules
if none are known for the specific server.
$CACHE_DIR = "/var/spool/pwhois/"; # Whois information will be
cached in this directory. Default is no cache.
$CACHE_TIME = 24; # Cache files will be cleared after not accessed
for a specific number of hours. Documents will not be
cleared if they keep get requested for, independent
of disk space. Default is not to clear the cache.
$USE_CNAMES = 1; # Use whois-servers.net to get the whois server
name when possible. Default is to use the
hardcoded defaults.
$TIMEOUT = 10; # Cancel the request if connection is not made within
a specific number of seconds.
Note: as of version 0.21, extra data will be loaded only if the
OMIT_MSG or CHECK_FAIL flags were used, in order to reduce memory usage.DESCRIPTION
Net::Whois::Raw queries NetworkSolutions and follows the Registrar: answer for ORG, EDU, COM and NET domains. For other TLDs it uses the whois-servers.net namespace. ($TLD.whois-servers.net).
Setting the variables $OMIT_MSG and $CHECK_FAIL will match the results against a set of known patterns. The first flag will try to omit the copyright message/disclaimer, the second will attempt to determine if the search failed and return undef in such a case.
IMPORTANT: these checks merely use pattern matching; they will work on several servers but certainly not on all of them.

Modified pattern matching, added cache. (Tony L. Svanstrom tony@svanstrom.org)
CLARIFICATION
As NetworkSolutions got most of the domains of InterNic as legacy, we start by querying their server, as this way one whois query would be sufficient for many domains. Starting at whois.internic.net or whois.crsnic.net will result in always two requests in any case.
NOTE
Some users complained that the die statements in the module make their CGI scripts crash. Please consult the entries on eval and die on perlfunc about exception handling in Perl.
