Request header: content-length

This will allow browser and download tools show a loading bar, tell me the process and keep me patient.
More importantly, without content length,it would just wait for the additional bit that would never come.

Today I tried with wget, and wget is not able to handle Content-Disposition: filename="my.pdf" and saved it to index.html instead.
I would appreciate it if you can add this.
