[users@httpd] Why include Content-Length in type-maps?
Are there any benefits of including Content-Length in type-maps? I do not understand the need to overwrite this option when Apache is perfectly capable of retrieving the information on it’s own.
Are there performance benefits of including it?

Oh, I bet that apache won't bother trying to determine the
content-length of all those files if you don't specify it explicitly.
Too much work for too little gain. If you want that, just go with
MultiViews rather than a type-map.

It is a negotiation criteria. I think what he is trying to ask about is: why
he should manually include it in the type-map instead of letting Apache
gather the file size automatically.

Without checking the code I'm just guessing, but it could be that the
content-length is used as a negotiation criterion: if all else
matches, choose the smallest representation.
