Web Address Validation

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

Write a script which will read a server log file and return the percentage of addresses which are businesses. Can you modify the script so that it will print out the name of the business (e.g ikea,tesco) and how often they were hit. You will have to make some assumptions about how the name of the company is stored in its web address. http://www.tesco.com http://www.mmu.ac.uk http://www.amazon.com http://www.ikea.co.uk http://plus.maths.org Any help would be greatly appreciated.

As you seem to have simply pasted your programming assignment here without showing where you have the actual problem, here are some interesting modules that will mostly solve this problem when put together in the correct sequence. Finding that sequence is called "programming" and something you have to do yourself. Parse::AccessLog Domain::PublicSuffix	[reply]

If this assignment were part of an obfuscation contest, I would say this: `$_=$,;$,=$/;$/=$_;$_=<DATA>;print/([-_a-z_-]+)\x2eco(?:m\|m?\x2e[a-z][a +-z])\s/gi; __DATA__ http://www.tesco.com http://www.mmu.ac.uk http://www.amazon.com http:/ +/www.ikea.co.uk http://plus.maths.org` [download]	[reply] [d/l]

I am most interested to see who will find a good rule to check which URL links to a business. CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout.

`m#\.co(?:m\|m?\.[a-z][a-z])/?$#` is the first thing that comes to mind without actually hitting the network. .com stands for commercial ... well, once stood for. Nobody seems to remember what it is supposed to be used for anymore :(	[reply] [d/l]
