Generated nginx.conf bug causes it to always use PHP to server cached pages

Hello,

Sorry for posting it here but didn’t know if it was the right place or not.

W3 Total Cache version: 0.9.4

The generated nginx.conf uses $w3tc_rewrite in all filenames for match which causes it to append a 1 after index.

This makes nginx fail all checks for file existence and, as such, fallback to php to serve the contents (still cached).

Lines with error:

set $w3tc_ext "";
if (-f "$document_root/mw-public/cache/page_enhanced/$http_host/$request_uri/_index<strong>$w3tc_rewrite</strong>.html") {
    set $w3tc_ext .html;
}
if (-f "$document_root/mw-public/cache/page_enhanced/$http_host/$request_uri/_index<strong>$w3tc_rewrite</strong>.xml") {
    set $w3tc_ext .xml;
}
if ($w3tc_ext = "") {
  set $w3tc_rewrite 0;
}
if ($w3tc_rewrite = 1) {
    rewrite .* "/mw-public/cache/page_enhanced/$http_host/$request_uri/_index<strong>$w3tc_rewrite</strong>$w3tc_ext" last;
}
