you are right.
Not only that rule, but also all other rewrite rules, leave them "as is", without change. for complex rewrite rules, it's very tricky and risky to change anything.
good question - there is a better solution. and we've been just aware that not a long time ago.
I'd publish the new suggested rewrite rules by this chance:
usually there exists such a rewriterule in .htaccess of document root:
RewriteCond %{HTTP_HOST} !^www\.mysite\.org$
RewriteRule...
build php for lsws, matching php for apache.
you can compare phpinfo() under apache and lsws.
refer wiki:
http://www.litespeedtech.com/support/wiki/doku.php?id=litespeed_wiki:php:lsapi
also, you change the default setting
PHP_LSAPI_CHILDREN=35
to
PHP_LSAPI_CHILDREN=50
then have you changed
Max Connections:35
as well? should change it to 50 as well. these 2 settings should match
