I've noticed an issue with the Alias field when creating documents and suspecting this might be a bug that will seriously affect SEO.
When creating a document with an alias e.g download-1 and saving it, if I then go and rename the alias e.g download-document-1, then both old and new alias are accessible and load the same page.
This means that if you require to rename the alias, you MUST place a 301 redirect, otherwise you'll end up with multiple URLs for the same page.
I've tested this with the latest version of edocman and believe this must be a bug of some sort. Once an alias is renamed, edocman should update its internal database and remove the old alias from it.
I'm not sure if the same thing is happening with the the categories alias's, but suspecting they too might be suffering from the same issue.
Thanks,
