regex - How do I convert mod_rewrite (QSA option) to Nginx equivalent?

Question

I'm looking to convert the following mod_rewrite rule to the Nginx equivalent:

RewriteRule ^foo/(.*)$ /bar/index.php?title=$1 [PT,L,QSA]
RewriteRule ^foo/*$ /bar/index.php [L,QSA]

So far I have:

rewrite ^foo/(.*)$ /bar/index.php?title=$1&$query_string last;
rewrite ^foo/?$ /bar/index.php?$query_string break;

The problem is (I think!) that the query string doesn't get appended. I haven't found a way to port the QSA argument to Nginx.

QSA is automatic in NGINX.

If you don't want it, add ? to the end of your new location

rewrite ^/foo /bar/index.php? last;
