Question: ETag headers for static files

[njlr]

Is there already a mechanism for serving files with the ETag header properly set?

Given the cost of computing the ETag (likely a hash of the file) I think this should be an opt-in feature.
To amortize the cost of hashing, we may want to leverage FileSystemWatcher.

If not, happy to send a PR with a bit of design direction.

We do not have such mechanism. Certainly it would be nice if Suave had a way of generating etags, I am interested in seeing what you have in mind. :)
