Hello

I have urls like [example.com/123](http://example.com/123)  
I need them rewritten to [Example Domain](http://example.com/?v=123)

However, I want to skip certain directories from rewrite  
eg.  
[example.com/status](http://example.com/status)  
[example.com/admin](http://example.com/admin)

right now I have this:

if (!-e $request\_filename){  
rewrite ^/([A-Za-z0-9-]+)/?$  
[http://www.example.com/v.php?dl=$1redirect](http://www.example.com/v.php?dl=$1redirect);  
}

Problem is that all urls are rewritten… how do I put some exceptions?

Thanks for any suggestion

put the rewrite in a location block (e.g. inside location / { }).

I would recommend using location matching to differentiate URIs  
which should be handled differently. E.g.

```
location / {
    # you may want to use try_files here instead
    if (...) {
        rewrite ...
    }
    ...
}

location /status {
    ...
}

location /admin {
    ...
}

```

See [Module ngx\_http\_core\_module](http://nginx.org/r/location) for more information.

Maybe something like this.

location = / {  
if ($arg\_v) {  
rewrite ^ /v.php?dl=$arg\_v;  
}  
}

Excellent, it worked

I have another urgent matter on a server live we just switched to

I need that links like this:  
[http://www.example.com/?v=JYH253CT](http://www.example.com/?v=JYH253CT)

to be rewritten as [http://www.example.com/v.php?dl=JYH253CT](http://www.example.com/v.php?dl=JYH253CT)

Please help, server is down ☹

I tried this from a htaccess to nginx converter

if ($query\_string ~ “^v=(.\*)$”){  
rewrite ^/index.php$ /v.php?dl=$1 break;  
}

But the resulting url is /v.php?dl=%1&v=FER34S

beats me!!

Try:

if ($arg\_v) {  
rewrite ^ /v.php?dl=$arg\_v break;  
}

Yes, this worked, I was also trying to get an idea of that matching in  
my  
attempt…

Why is $1 not matching right?
