176	Error handling fallback with variables when using try_files in a location with an alias	Jonathan Kolb	somebody	"When the fallback for a try_files in a static location with an alias set contains variables and expands to a value that starts with the location text, the resulting redirect leaves off the location text.  This is not what I would expect.  Here's an example:

    # test: alias + try_files fallback
    # expected result: internal redirect to /test/index.php
    # result: internal redirect to /index.php
    location /test {
        alias /doesnt/exist;
        try_files $uri $uri/ /test/index.php?$args;
    }

and here's the debug log output generated from an error_log defined in that location:

2012/06/14 14:17:52 [debug] 17647#0: *15 internal redirect: ""/index.php?""

If the fallback doesn't contain variables, then the try_files behaves as expected:

    # test: alias + try_files fallback
    # expected result: internal redirect to /test/index.php
    # result: internal redirect to /test/index.php
    location /test {
        alias /doesnt/exist;
        error_log /tmp/error.log debug;
        try_files $uri $uri/ /test/index.php;
    }

and debug log output:

I can try reproducing without any third party modules if you need me to, but I don't think it'll make a difference."	defect	closed	minor		nginx-core	1.3.x	duplicate				"nginx version: nginx/1.3.1
