You've shown a "try_files" directive, but no rewrite directive.

Quick testing indicates that for try_files, the answer is "yes and no",
with a fuller explanation below.

http://nginx.org/r/try_files indicates that it means "take these urls
in turn, convert them into filenames by prefixing the relevant 'alias'
or 'root' value, and for the first such file that exists, process the
corresponding url normally".

So with the above line, unless you have a "typo3temp" directory inside
/usr/local/nginx/html, it is going to fall back to the @location every
time.

Once that is fixed, then if the index.html file does not exist, try_files
will fall back to the @location (so "it does not heed gzip_static"). But
if index.html does exist, then processing continues of that url -- which
will serve index.html.gz if appropriate (so "it does heed gzip_static").

Overall: try_files is not aware of gzip_static; but nginx will still
honour it if both the non-gz and .gz files exist. This differs from
the "normal" gzip_static handling which will serve the .gz version if
appropriate, whether or not non-gz exists.

So long as both index.html and index.html.gz are there, try_files should
Just Work.

I tested this on a 1.2.0 build, in case that matters.

rewrite can be tested separately, if you have a sample directive.
