file tests in subfolder and rewriting

[Boris Bartsyts]

hello,

i can't make nginx check for existence on the file in a subfolder:

    if (-f /cache$request_filename) {
        rewrite ^(.*)$ /cache$1 break;
    }

and with a variable:

    set $file /cache$request_filename;

    if (-f $file) {
        rewrite ^(.*)$ /cache$1 break;
    }

both methods fail. i've tried to add nother / before $request_filename,
with no luck. ideas, anyone?

Boris
