There are multiple kinds of redirects.

Permanent Redirects.

A permanent redirect is a sign that a resource has been moved. You would use it, for example, if you changed internet provider and had to change where your pages were, or if you moved a page around within your web site.

Permanent redirects are the correct way to signal a change of link, and if everything worked properly, detecting these would be about the main job of a link checker. It doesn't of course.

Temporary Redirects

According to the HTTP definitions, a temporary redirect is just telling a client (e.g. your browser) that it would be better to get the document it wants from somewhere else right now, but that later it will be back here.

Examples of use could be someone who has five or six different servers. By giving out a different redirect at random from the primary server, the load can be spread evenly between the others. Of course, there are much better ways of doing this, but we have to be ready for everything.

In the above examples you wouldn't want to change the link. Just tell the link maintainance system that you don't want to be bothered about this redirect again.

It is also possible that someone has chosen the wrong kind of redirect through some kind of misunderstanding. The symptoms would be

  • the redirect wasn't there before

  • the redirect only goes to one page

  • the pages mention the new redirect
