Multiple named locations in try_files

Server NGINX
#1

Hello.

According to english wiki, named locations may be used for other
purposes than fallback :
http://wiki.nginx.org/NginxHttpCoreModule#Named_Locations

However when i tried “try_files @tier_ssi @tier_php” i observed the
following behavior in error_log debug:
2009/12/05 18:53:30 [debug] 19908#0: *399 try to use file: “@tier_ssi”
“/usr/local/nginx/[email protected]_ssi”
2009/12/05 18:53:30 [debug] 19908#0: *399 try to use file: “@tier_php”
“/usr/local/nginx/[email protected]_php”
2009/12/05 18:53:30 [debug] 19908#0: *399 test location: “@tier_php”
2009/12/05 18:53:30 [debug] 19908#0: *399 using location: @tier_php “/?”

location @tier_php was tested first even though @tier_php was first in
try_files and location @tier_ssi ws not tested at all.

meanwhile my confiuration defined both location @tier_ssi {} and
location @tier_php {}

This behavior leads me to believe that nginx allows named location
only at the end of try_files, but documentation contradicts it. Which
is correct?

Ideally i would like to be able to do try_files with multiple named
locations first being tier_ssi and second being tier_php fallback. my
tier_ssi try_files is a php fastcgi_pass to a different backend that
returns some content (and appropriate response headers). if tier_ssi
try_files returns with 404 header it would attempt tier_php in
try_files. tier_php on the other hand is proxy pass to a backend
different from fastcgi_pass in tier_ssi.

Please advise.
Thank you.

btw you can have the same file parsed for SSI and PHP :slight_smile:

neat little trick i realized which was nice, since one of my clients’
sites was designed that way (don’t ask…)

You are correct http://wiki.nginx.org/NginxHttpCoreModule#try_files

If you read try files documentation try_files test for files existance
and if none are found it goes to fallback which can be a named
location. So named locations are only allowed for the fallback as
documented.

location / {
# tier_ssi
fastcgi stuff

   fastcgi_intercept_errors  on;
   error_page  404   = @tier_php;

}

location @tier_php {
…
}

Sometime after posting to mailing list i came to the same solution.
