In my wordpress Multisite config, I have the below lines. I've read if-is-evil and so I'm curious if these ifs need to be replaced and with what?

# For multisite: Use a caching plugin/script that creates symlinks to the correct subdirectory structure to get some performance gains.
set $cachetest "$document_root/wp-content/cache/ms-filemap/${host}${uri}";
if ($uri ~ /$) {
set $cachetest "";
}
if (-f $cachetest) {
# Rewrites the URI and stops rewrite processing so it doesn't start over and attempt to pass it to the next rule.
rewrite ^ /wp-content/cache/ms-filemap/${host}${uri} break;
}

if ($uri !~ wp-content/plugins) {
rewrite /files/(.+)$ /wp-includes/ms-files.php?file=$1 last;
}

# Uncomment one of the lines below for the appropriate caching plugin (if used).
# include global/wordpress-ms-subdir-wp-super-cache.conf;
# include global/wordpress-ms-subdir-w3-total-cache.conf;

# Rewrite multisite '.../wp-.*' and '.../*.php'.
if (!-e $request_filename) {
rewrite ^/[_0-9a-zA-Z-]+(/wp-.*) $1 last;
rewrite ^/[_0-9a-zA-Z-]+(/.*\.php)$ $1 last;
}
