[edit] Discussion

How will the bot know if a link is dead of if the server is temporarily down? —METS501 (talk) 23:36, 23 March 2007 (UTC)

The dictionary is human generated and verified. The bot currently checks the content-type to see if it's either application/PDF or octet-stream, so it doesn't report the size of 404 pages. I plan on using it on the VA highway pages, see [1]. —Dispenser 00:29, 24 March 2007 (UTC)

Sorry, I don't understand :-( Not your fault. You can either try to explain it more step by step to me or wait for another BAG member or user. —METS501 (talk) 01:46, 24 March 2007 (UTC)

The WikiProject U.S. Interstate Highways has been using www.virginiadot.org as a reference and tagged the pages with PDFlink. About half a year ago, I believe, virginiadot had moved their resources to a different directory. To fix these URLs is trivial, but since I did not ask for it in my original request I can't do it. Thus, I'm filling out a second request to cover fixing URLs. —Dispenser 03:34, 24 March 2007 (UTC)

With the content-type precautions you've made and the use of a manually created list of what to replace in the URL to get it to work, I don't see any problem with the idea. However, in the diff you referenced above, the PDF size isn't shown in brackets afterwards (the parameter having been removed). Is this a problem present in the bot, or is it just the fact that you were carrying out the replacement manually? Also, I'd just like to seek assurance that the bot does check that the new links work before replacing the old ones with them, to avoid any problems with some dead links being introduced.

The manual removal the parameter was done since it was incorrect (those were the size of the 404 html) and is not reflective of the bot would do. The links will pass the normal (correct content-type) tests before they are committed. —Dispenser 22:08, 24 March 2007 (UTC)
