How does the QUICK CHECK IO Method actually work?
Hi!

I ran it on some links I have on the DB and get things like:

Code:
Took: 85 seconds to check 87 links.

Bad Link Summary
-----------------------------------------------
95 - http://www.areatv.com/webcam/ [modify|delete] : 404 - File Not found
4 - http://www.webcamworld.com/webcams/ [modify|delete] : 404 - File Not found
43 - http://compservice24.com/webcam.html [modify|delete] : 302 - Found, but data resides under different URL (a
25 - http://www.mastnet.net/~jgray [modify|delete] : 301 - Found, but moved

Check for yourself. They exist!

Some of the errors say Add a /
Do you really check all the database entries for missing /'s???

How does the IO port method works?
Why does it fail?
How do I install the LWP module?
Is it far better?
Running under linux...

Any ideas?

Thanks!

Well, I don't know how IO or LWP works, but I can answer one question: Unfortuately, you really should have trailing slashes where appropriate. Every links verifier I have ever used has given me a "page moved" type response when the trailing slash is left off. That's why I make sure I add it to new submissions when needed.

Do you only get a lot of 404's for pages that are really there, or just a few?

Let's say something between not that much and more than a few ;-)

Why?

I'll chime in on the subject, but conveniently avoid answering any questions. Smile

I could never get the verify routines to work after my database exceed 200 or so links. I just moved to a new server, and suddenly verify started working. It still times out, or gets stuck about half way through everytime (600 out of 1260 links), but it's definite progress! Similarly, I always had to do staggered builds before, due to timing out, but on the new server the build all works flawlessly every time. So, to make a long story short, it all seems very server dependant.

I, too, noticed that the verifier is much happier if you add any necessary trailing slashes. And I've encountered at least one page that keeps throwing it for a loop (301 or 302, found but moved) where the link is correct. But I haven't noticed any such problems for 404's.
