Hello,

I want something like limit_except functionality but based on custom request headers. Lets say I have a Request header X-Secured-Client set. In that case only I want to allow the request to my upstream server.

How can I achieve that without using "if" blocks? (I did search the mailing list with no success).

If the above requirement is possible, can I check if the header value is set to say 1 to allow the request to upstream server else send 444 back.

Thanks for any help,
Shreyas
