Getting the URL of a referer

ACJavascript has asked for the wisdom of the Perl Monks concerning the following question:

Hello all,

I SEEK THE WISDOM OF THE PERL MONKS! hehe

Okay I need to know this:
Say the referer is http://www.yahoo.com/s=2342&stuff=asdfsd

I read the referer using ENV{'HTTP_REFERER'} - NOW
How can I split it up so that All I have like is www.yahoo.com?

Im pretty sure its going somthing to do with substr but I can't figure it out. Please any help would be most appreciated!

Alternately, use the URI module and the `host()` method.	[reply] [d/l]

First, this "http://www.yahoo.com/s=2342&stuff=asdfsd" is a URL; this "www.yahoo.com" is a domain name or host name. Second, be aware that the referer is not always present. There are many ways to do this (say, maybe that should be a slogan :-). The best way, if you have the URI module installed, is this: `use URI::URL; my $host = URI::URL->new($ENV{'HTTP_REFERER'})->host;` [download] That will handle more obscure cases, such as "https://joe@www.yahoo.com:4040/fred?billy".

Yours is so close I can't help but wonder if you already know it and the smiley emoticon is hinting at the slogan. Here t'is: TIMTOWTDI: There Is More Than One Way To Do It	[reply]

Rather than "do it for you", have a look at this link... then you'll be able to do it yourself. Much more satisfying that way. ;)	[reply]
