Hi,  
for the http header Nginx Nginx convert the dashes in the header name  
to  
underscores.  
I have a query string with a param with a dash in the name, but i can’t  
see  
it with $arg\_PARAMETER variable.  
There is a way to have the value of this parameter in a variable?  
For example my query string is:  
response-content-disposition=attachment  
I know i can parse manually the query string, but I think if there is an  
Nginx embeded function, this function could by faster than a manual  
parsing.  
Regards,

Luca
