amazon s3 - nginx try_files with s3 bucket and proxy_pass for html pages without extension -

i have s3 bucket contains directories , html files. i'm using nginx in front of bucket , have configured proxy_pass bucket, works fine. want clean urls without html extension, , these urls resolve properly. example, instead of foo.com/bar/my-file-name.html, must accessible @ foo.com/bar/my-file-name

the primary question here how prevent requiring .html @ end of every url. in, want nginx handle routing each requests , try looking file .html extension, , return it.

my problem can't figure out how force nginx try_files on non-s3 site. when try , add configuration of try_files, breaks site returning http 500 errors on paths.

for comparison, here configuration works great on non-s3 backed site (with files on server itself):

location / {     try_files $uri $uri/ @htmlext; }  location @htmlext {     rewrite ^(.*)$ $1.html last; } 

my goal replicate behavior proxy_pass s3 bucket , force try filenames .html extension other index.html, works out of box.

here current configuration works great, minus html files other index.html:

location / {       proxy_pass my-bucket.s3.blahblah/; }
