I'm trying to figure out if google or any other service would treat apache folder pages as duplicate content if in each access attempt a random number of slashes are used. For example, these four URLs would produce the exact same file listing:
http://example.com/folder http://example.com//folder http://example.com/folder/ http://example.com/folder// http://example.com//folder///
If so, am I better off making an apache module to redirect the URLs above to just one, or should I make a module that reproduces the directory listing but adds a directive for robots to not index the pages, or is there a special apache directive I can use to solve this issue, or can I just do nothing and assume Google treats directory listings differently from regular webpages?
I don't want to disable directory listings tho as some clients with lack of knowledge of computing require access to them.
