I have two more questions about this: 1. I can use any regular expression supported by PCRE, anywhere in my nginx config, correct?
The regexp engine is PCRE.
The regexp are supported in some directives only: "if", "rewrite", and "location".
2. When I have nested locations, such as: location / { location /api/receive { break; } some_config_option on; }
Configuration options in the outer scope (location /, in this case) are always evaluated, despite the break command? In other words, break only 'breaks' from the location / rewrite loop, not from the rest of the configuration?
If the "rewrite" directive has rewritten URI, then nginx search the new location configuration. The "break" stops this rewrite cycle.
The nested locations are not fully supported, you should use
location / { ... }
location /api/receive { ... }
Sorry to belabor the point, but this is really helping me understand.
location / { set $once = "once"; if ($once) { set $once = ""; rewrite ^ /once break; } set $once = "twice"; rewrite /once /twice break; }
Given that code (assuming it is valid.. if not, let's pretend I wrote it correctly).
I would expect that a request for example.com/ would be rewritten to example.com/once, and that the value of $once would be 'twice'.
Am I correct about that? My understanding is that break cancels any further rewrites, but has no effect on the other configuration statements that come after it.
