I have read a dozen rewite questions. Most questions are for .php but I have simple .html files so about => about.html .But I am not able to get nginx to do this:

* accept url with or without "/"
* redirect domain.com/about and domain.com/about/ to domain.com/about.html
* add trailing slash to the URL so if I write domain.com/about it writes domain.com/about/

I have tried with this code
`rewrite ^/([a-zA-Z0-9]+)$ /$1.html;`
but it gives me 404 error on url ending with "/". Also tried this 
`rewrite ^([a-zA-Z0-9]+)/?$ $1.html` with same error.

Some suggest I should be using try `try_files`?

I tried this also which gives a 500 error:

```
location / { 
rewrite ^(.*)$ /%1 redirect; 
rewrite ^/([^\.]+)$ /$1.html break; 
}

```

I tried to convert apache to nginx (winginx.com) from suggestion [here](https://stackoverflow.com/questions/21417263/htaccess-add-remove-trailing-slash-from-url?rq=1) with no success. 

This code does not work. I am trying to redirect and add trailing slash:

```
if (!-e $request_filename){
rewrite ^/(.*)/$ /$1 redirect;
}
if (!-e $request_filename){
rewrite ^/(.*[^/])$ /$1/ redirect;
}

```

Any suggestion would make me happy.
