I have a caching system I need to bypass if the user's name (in a cookie) is found in the $request_uri. I'm trying to do something like this, but can't get the variable to interpolate into the regex. Any suggestions pretty please?
I can set the $me variable just fine from the cookie; I just can't get it to interpolate into the regex.
set $chk == "need"; set $me "kevin"; if ($uri ~ $me) { set $chk ""; } if ($chk == "need") { rewrite ^ /testing } I've always tried things like this:
if ($uri ~ "by-{$me}") { set $chk ""; } Thanks! -Kevin

Note: Regex can be created in two ways first one is regex literal and the second one is regex constructor method ( new RegExp() ). If we try to pass a variable to the regex literal pattern it won't work. The right way of doing it is by using a regular expression constructor new RegExp() .
Nginx uses the PCRE library.
The map module is a core Nginx module, which means it doesn't need to be installed separately to be used. To create the necessary map and redirect configuration, open the default server block Nginx configuration file in nano or your favorite text editor.
To find a location match for an URI, NGINX first scans the locations that is defined using the prefix strings (without regular expression). Thereafter, the location with regular expressions are checked in order of their declaration in the configuration file.
It's not exactly what I asked, but I think it'll work for my purposes. I'm still curious how to interpolate a variable inside a nginx PCRE regex if anyone else knows!
set $chk == "need"; set $me "kevin"; if ($uri ~ /by-([^-]+)/) { set $by $1; } if ($by = $me) {set $chk "";} If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
