Notice that we have multiple directories created for a given post depending on the case used when linking to the post from a 3rd party site
...will result in two directories being cached:
More will be added depending on the creativity of the person linking to the site externally.
Is there anything that can be done to prevent this?
A similar issue we are seeing related to erroneous 3rd party links are when the URL is linked at the end of a sentence and a period is included:
I really like the website http://mydomain.com.
The result is 2 supercached subdirectories being created:
While these are not so much of an issue for smaller sites, for sites with significant volume this can create quite a duplication of server effort in trying to maintain multiple cached copies of the same posts.
Any suggestions on how best to handle this?
