I suspect that you may need to use one of the programming language  
modules available in your nginx to do that.

Why do you want to do it?

Perhaps there is an alternative acceptable way to achieve your final  
desired result.

Hi,  
I using third-party software,  
in some cases users create not valid url, and I want to fix it  
for example:  
[http://xx.yy/xx/yy/?a=1&b=1](http://xx.yy/xx/yy/?a=1&b=1) 2 3.txt  
need replace by:  
[http://xx.yy/xx/yy/?a=1&b=123.txt](http://xx.yy/xx/yy/?a=1&b=123.txt)
