Get a list of URLs from a site

I'm deploying a replacement site for a client but they don't want all their old pages to end in 404s. Keeping the old URL structure wasn't possible because it was hideous.

So I'm writing a 404 handler that should look for an old page being requested and do a permanent redirect to the new page. Problem is, I need a list of all the old page URLs.

I could do this manually, but I'd be interested if there are any apps that would provide me a list of relative (eg: /page/path, not http:/.../page/path) URLs just given the home page. Like a spider but one that doesn't care about the content other than to find deeper pages.

I didn't mean to answer my own question but I just thought about running a sitemap generator. First one I found http://www.xml-sitemaps.com has a nice text output. Perfect for my needs.

do wget -r -l0 www.oldsite.com

Then just find www.oldsite.com would reveal all urls, I believe.

Alternatively, just serve that custom not-found page on every 404 request! I.e. if someone used the wrong link, he would get the page telling that page wasn't found, and making some hints about site's content.

Here is a list of sitemap generators (from which obviously you can get the list of URLs from a site): http://code.google.com/p/sitemap-generators/wiki/SitemapGenerators

The best on I have found is http://www.auditmypc.com/xml-sitemap.asp which uses Java, and has no limit on pages, and even lets you export results as a raw URL list.

It also uses sessions, so if you are using a CMS, make sure you are logged out before you run the crawl.

So, in an ideal world you'd have a spec for all pages in your site. You would also have a test infrastructure that could hit all your pages to test them.

You're presumably not in an ideal world. Why not do this...?

1. Create a mapping between the well known old URLs and the new ones. Redirect when you see an old URL. I'd possibly consider presenting a "this page has moved, it's new url is XXX, you'll be redirected shortly".

2. If you have no mapping, present a "sorry - this page has moved. Here's a link to the home page" message and redirect them if you like.

3. Log all redirects - especially the ones with no mapping. Over time, add mappings for pages that are important.

wget from a linux box might also be a good option as there are switches to spider and change it's output.

EDIT: wget is also available on Windows: http://gnuwin32.sourceforge.net/packages/wget.htm

Write a spider which reads in every html from disk and outputs every "href" attribute of an "a" element (can be done with a parser). Keep in mind which links belong to a certain page (this is common task for a MultiMap datastructre). After this you can produce a mapping file which acts as the input for the 404 handler.

I would look into any number of online sitemap generation tools. Personally, I've used this one (java based)in the past, but if you do a google search for "sitemap builder" I'm sure you'll find lots of different options.
