nginx setup with conditional reverse proxy for some routes

Question

I have a laravel server fronting a wordpress hosted on another server. The laravel server is receiving all traffic. I would like to direct specific routes to the local index.php (laravel) and all others to the wordpress. Like this:

/a/* --> laravel server (localhost) /b/* --> laravel server (localhost) /* --> wordpress (separate server) 

My nginx conf currently has this:

index index.html index.htm index.php; location ~* /[a|b]/.+ { try_files $uri $uri/ /index.php?$query_string; } location ^~ / { proxy_pass https://10.0.1.44; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } 

The wordpress is receiving all routes. How can I force /a/* and /b/* to get served by index.php on the local server?

The problem is location ^~ / directive. This makes the prefix match explicit and prevents nginx from looking at regular expression matches.

Try the following:

location ~*^/[ab] { try_files $uri $uri/ /index.php?$query_string; } location / { proxy_pass https://10.0.1.44; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }
