    initial v1  
    33For "/", when rewrite gets to @cgicache by following 418 returns, it executes the "set" directive and stops. Since no "if" selected another configuration, and no "break" was used, a changed uri then matches the "/" location and is processed with the static file content handler.

    5 By putting a "break" inside @cgicache tell rewrite to stop rewriting and assign a request the containing location.  And in this location, the content handler memcached.
     5By putting a "break" inside @cgicache you tell rewrite to stop rewriting and assign the request the configuration of containing location.  And in this location, the content handler is memcached.

    7 Now, if you comment memcached but retain "break", the content handler is inherited from the implicit server location, which happens to be "index" content handler (since uri ends with "/"). Index first checks root+uri+index file, /my/root/showpage/index.html, fails, then tests if a directory exists (to return either 403 or 404), and since there's no directory, returns 404 which is then internally redirected to @cgipass. There, uri gets rewritten to /cgi-bin/showpage.fcg/, and rewrite module finishes. The uri then matches the "/" location with the static file handler, which is probably not what you wanted. But you already know how to solve it.

Index first checks the root+uri+index file, /my/root/showpage/index.html, fails, then tests if its parent directory exists (to return either 403 or 404), and since there's no directory, returns 404 which is then internally redirected to @cgipass. There, uri gets rewritten to /cgi-bin/showpage.fcg/, and rewrite module stops. The uri then matches the "/" location with the static file handler, which is probably not what you wanted.
