Description
I would like to set this header in a location:
proxy_set_header X_DBFILTER '^db-main$';
But it fails:
nginx: [emerg] invalid variable name in /etc/nginx/nginx.conf:121
I tried these, but again fails:
proxy_set_header X_DBFILTER '^db-main\$'; proxy_set_header X_DBFILTER '^db-main$$';
Please make it to work, it would be a very basic functionality!
My suggestion is to make the $$ chars to mean the $ char.
Note:
See TracTickets
for help on using tickets.
To make this bug easier to find, it is about a literal dollar character in strings. I agree that
$$makes the most sense because any other character may already be present in existing configs which could corrupt them.
