Hi guys,

I’m trying to rewrite an url with a few parameters, but unsuccessfully.

The URL:

[https://www.mysite.com.br/category-body/categories/promotionalXXX?utm\_source=PromoCode&utm\_medium=AddPromo&utm\_campaign=PromoCode\_AddPromo\_moneycampaing](https://www.mysite.com.br/category-body/categories/promotionalXXX?utm_source=PromoCode&utm_medium=AddPromo&utm_campaign=PromoCode_AddPromo_moneycampaing)

I need rewrite to:

[https://www.mysite.com.br/digital-parts/newspaper/recs-xyaw-sazz-qqad-cxae](https://www.mysite.com.br/digital-parts/newspaper/recs-xyaw-sazz-qqad-cxae)

The /promotionalXXX can be /promotional123, /promotional324 and many  
more  
…

What i already tried:

rewrite  
^/category-body/categories/promotional(.\*)utm\_source=PromoCode&utm\_medium=AddPromo&utm\_campaign=PromoCode\_AddPromo\_moneycampaing  
[https://www.mysite.com.br/digital-parts/newspaper/recs-xyaw-sazz-qqad-cxae](https://www.mysite.com.br/digital-parts/newspaper/recs-xyaw-sazz-qqad-cxae);

and …

location = /category-body/categories/promotional(.\*)$ {  
if ($args ~  
utm\_source=PromoCode&utm\_medium=AddPromo&utm\_campaign=PromoCode\_AddPromo\_moneycampaing)  
{  
rewrite ^/digital-parts/newspaper/recs-xyaw-sazz-qqad-cxae; permanent;  
}  
}

But any of this worked for me…

What’s the best way to solve this?

Thanks!

You’re almost there 😉

“rewrite” doesn’t examine query strings, so if the contents of your  
query string are required to drive your logic, you’ll need to use  
other tools instead of (or well as) rewrite.

You probably don’t want the “=” here. I don’t actually know what a  
regex (“(.\*)”) location used alongside “=” will do. I’m slightly  
surprised nginx didn’t complain on reload/restart …

Have a read of this section:  
[http://wiki.nginx.org/HttpCoreModule#location](http://wiki.nginx.org/HttpCoreModule#location)

You probably want to use a case-sensitive regex location.

“utm\_source=PromoCode&utm\_medium=AddPromo&utm\_campaign=PromoCode\_AddPromo\_moneycampaing”)

I’d use a map{} variable inside the if(), personally. The map can use  
the same check as that which you have above, but in a way which  
abstracts the actual check away from the logic that it drives. This is  
just a stylistic change however 🙂

HTH,
