Hi Maxim,  
Many thanks to your work!

I am using auth req module and have experienced the following problem  
(issue).  
I can’t get the headers to be passed to auth backend from initial  
request.

location /initial {  
auth\_request /auth  
}

location /auth {  
proxy\_pass ;  
proxy\_set\_header X-Header $http\_x\_header\_from\_request;  
}

Unfortunately, auth service does not receive the X-header.  
Do I understand correct that auth\_req module does not receive headers  
from  
initial request?

Thanks in advance,  
Oleksiy

It works,  
you have to put header in quotes:  
“$http\_x\_header\_from\_request”

Hello mokriy,

Are you using the perl script that Maxim included with auth\_request or  
are  
you doing it some other way?

I am working to setup auth\_request using my own form and with a CGI  
program  
in C but I would be very interested in what you are doing.

What does “” represent in your nginx.conf?

Thank you both very much.
