I’m porting a .asp application over to something else, and I need to  
re-write the following url pattern:

[www.example.com/posts/get\_post.asp?post\_id=123](http://www.example.com/posts/get_post.asp?post_id=123)

to

[www.example.com/posts/123](http://www.example.com/posts/123)

How can I do that?

location = /posts/get\_post.asp {  
return 301 /posts/$arg\_post\_id;  
}

So when nginx responds with a 301, is that an additional rountrip for  
the  
user?

Could I somehow maintain the url for the client, but internally re-write  
it  
to the updated url so my web application can handle it correctly?

rewrite ^ /posts/$arg\_post\_id;

so like this:

location = /posts/get\_post.asp {  
rewrite ^ /posts/$arg\_post\_id;  
}

correct?
