Webchecker Usage - a problem with local usage

[Colin J. Williams]

I have material on a local PC which I upload to a web server.

I would like to use webchecker to check both the local linkage and that 
at the remote server.

All works well when I check the remote server:  http://www3.sympatico. 
...  The URL for the index.html.

However, only the index.html is read when using: file:C:\\Python23/ 
...           The URL for the index.html.

The problem arises in the Checker method, where the basic structure of 
the url has been changed.  It no longer contains the root:

        def inroots(self, url):
            for root in self.roots:
                if url[:len(root)] == root:
                    return self.isallowed(root, url)
            return 0

It appears to be caused at urlparse lines 129 and 130,  where three '/' 
characters are prepended to the URL.

By commenting out lines 128, 128 and 130 of urlparse, I get the same 
report for the local files that I get from the web server.

I don't like modifying a library routine, even a local copy and would 
appreciate advice.

Thanks.
