The questions is how to find the pages where our old webmasters used relative urls taking into considerations that it is about 100 sites with 1000s of pages – what online service or software should we use?
We have tried [validator.w3.org...] and “web q a” software but they do not show it.
If you are seeing a canonical problem on these domains, I think a first and easier step would be placing the <base href=""> element in the head section of each page.
Are your pages static html files, or are they generated dynamically? If there are flat files, I would first experiment with a bulk search/replace utility on copies of the sites, just to take the measure of the situation. It might be easier than it sounds if recent development has adhered to your "absolute url" standard.
