The documentation on this directive states the following:
The files in this directory have to be PEM-encoded and are accessed through hash filenames. So usually you can't just place the Certificate files there: you also have to create symbolic links named hash-value.N. And you should always make sure this directory contains the appropriate symbolic links.
I have two questions about this:
- Practical: What is the .N part in the filename meant for? How do I decide which value to give it?
- Conceptual: Why doesn't Apache just scan the specified directory for certificate files? Am I missing some property that calculating and remembering the hash of a certificate provides?
