Try this instead:
location /compressed_files/ {
gzip_static always;
gunzip on;
}
See documentation here for additional details:
http://nginx.org/r/gzip_static
http://nginx.org/r/gunzip
Note that you wan't be able to combine this with "try_files
$uri.gz ...", as this will change URI as seen by gzip_static and
will break it. If you want to fall back to a different location
when there is no file, use "error_page 404 ..." instead.
