This function is designed to be called from within a FileLock context to avoid multiple processes downloading the same file. If the file is newer than `dont_check_if_newer_than_seconds`, then immediately return the cached contents. Otherwise we pass the ETag from the last download in the headers to avoid downloading the file if it hasn't changed remotely. z.etagr r NzError checking age of rzUsing cached mapping  of age zs without checking for updatesz If-None-Matchz Requesting ri0z, has not changed since last download, using ETagzNo ETag in response headersz Downloaded z to )r%r&is_fileget_age_seconds RuntimeErrorr)debug read_bytes read_textstriprr status_coder write_bytesrr write_textr*) r rr destinationdestination_etagrequest_headers age_secondsold_etagrs rr(r(Ps1#666K"..w77#\2O8%k22  E EEFF F > > > >> > > > > > LL0 00[000   ))++ +  # # % % 8'113399;;H/7OO , LL$s$$%%% ,sO 4 4 4C # VVVVWWWW  ,,, S[  ' ' F(; < < < < NN8 9 9 9 LL5s55 55666  ! ! # ##rctj|dd}|dd}t |dkrt jd|r|d|S|S)u Return a filename for a URL that is probably unique to the URL.
