Description

Problem seen since upgrading to version 1.4.50.

Version 1.4.49 is NOT affected, using same config.

URL to test (static file):

www.domain.tld/wp-content/uploads/2014/06/sample-29.png?id=623

ERROR shown at logs:

(mod_rewrite.c.243) ENDLESS LOOP IN rewrite-rule DETECTED ... aborting request, perhaps you want to use url.rewrite-once instead of url.rewrite-repeat

Config using "url.rewrite-if-not-file" (NO other mod_rewrite rules for the host)

        url.rewrite-if-not-file = ("^/wp-content/cache/minify/(.+\.(css|js))$" => "/wp-content/plugins/w3-total-cache/pub/minify.php?file=$1")

        url.rewrite-if-not-file += (
                "^/(forums|wp-admin|wp-includes|wp-content|storage)/(.*)" => "$0",
                "^/wp-admin$" => "$0",
                "^/(sitemap\.xml|sitemap\.xml\.gz)" => "$0",
                "^/(.*\.php)" => "$0",
                "^/(.*)$" => "/index.php/$1" 
        )

Changing "rewrite-if-not-file" to be "url.rewrite-once" works, but suspecting something weird is happening since it was working before (so breaking change..) and the log message about not using "url.rewrite-repeat"

ick. Looks like I messed up some indexes for url.rewrite-repeat and url.rewrite-if-not-file. Please try this patch:
