Hey guys!

I need to know if there’s a way to find out the content type of content  
going through the proxy before the logging process.

I can use $upstream\_http\_content\_type for logging the information, but I  
need to access the value before outputting the page to the browser. The  
http\_content\_type and send\_http\_content\_type variables mentioned on the  
Proxy page are empty.

Thanks in advance,
