Nginx with php-fpm + SSI

[ehsan310@…]

Hello,

we have a php-fpm configured with nginx fastcgi ,

The problem is we have SSI in our html files which mentiones location which is php-backend ,

When we open that location directly in browser , everythings works fine, but when we use SSI for the same location PATH_INFO is empty so our script doesn't work.

   location /backend { ## URL string to use for api ##
        alias /var/www/html/backend/web/; ## Site root for api code ##

        ## Check for file existing and if there, stop ##
        if (-f $request_filename) {
            break;
        }

        ## Check for file existing and if there, stop ##
        if (-d $request_filename) {
            break;
        }

        ## If we get here then there is no file or directory matching request_filename ##
        rewrite (.*) /backend/index.php?$query_string;

        ## Normal php block for processing ##
        location ~ \.php(?:$|/) {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_param PATH_INFO $fastcgi_path_info;
            fastcgi_param HTTP_IPCOUNTRY $geoip_country_code;
            fastcgi_pass php-handler;
            fastcgi_read_timeout 600; # Increase this to allow larger uploads
            access_log off; # Disable logging for performance
        }

    }

Look for a workaround in ticket:321

Please provide URI you use (and/or full SSI command you use), how you expect it to be handled, and how it's handled instead.

[ehsan310@…]

The URI is , ​http://IP/backend/site/home
This works fine when i open from browser and i have a expected output.

<!--# include virtual="/backend/site/home" -->

But SSI won't work with same path and i have a error from my backend.PATH_INFO is empty

[Maxim Dounin]

As per your configuration, the "/backend/site/home" is expected to be either:

• returned as static file (if appropriate file exists),
• or redirected to a URI with added "/" (if appropriate directory exists),
• or rewritten to "backend/index.php?$query_string".

In neither case PATH_INFO will be set.

I'm closing this ticket as it doesn't looks like a bug in nginx. If you have further question on how to configure nginx, please use ​support options available.

[ehsan310@…]

Let's make it more clear,

When i open example.html which have SSI inside , the request which will be sent to our backend side , will only have "/" as a URI,

But when we open "/backend/site/home" directly from browser PATH_INFO and URI will be sent fine.

The problem is i think when we use SSI , the URI request to "/backend/site/home" should be "/" or "site/home" ?

[Maxim Dounin]

You didn't provide enough information to understand what goes wrong in your configuration and why it happens. As a blind guess - note that when using default fastcgi_params, REQUEST_URI as sent to fastcgi application will be the original URI of main request, not an URI of SSI subrequest (see ticket #288). If you are using it in your scripts and expect it to match subrequest URI, consider using SCRIPT_NAME or DOCUMENT_URI instead.

As previously suggested, if you have further question on how to configure nginx, please use ​support options available.
