mod rewrite not working in LiteSpeed

    The rewrite in the .htaccess file worked on the old Apache server, but is not working in the LiteSpeed server 4.0.20. I heard it was fully compatible with Apache. Below is the code...

     RewriteCond %{REQUEST_FILENAME} !-f
     RewriteCond %{REQUEST_FILENAME} !-d
     RewriteCond %{REQUEST_FILENAME} !-l
     RewriteRule ^category/(.*) /$1?tab=category [P,L]
    This code causes a 500 Internal Server Error. The error in the log goes like this...
    [ERROR] [REWRITE] Absolute URL with leading 'http://' is required for proxy, URL: /aromatherapy.html

    Thoughts as to why this would work in Apache and not in LiteSpeed?

    You should remove the [P] flag, it is for proxy, not sure what apache will do, but proxy to the same server is a bad idea anyway.

    you need to create webserver external application and refer below for proxy rewrite usage.

    Modify proxy request "Host" header value, example:
    web site domain name is "", it proxy request to backend, backend is defined as a web server with name "node1", it requires domain name to be "", the rewrite rule should be
    RewriteRule ^(.*)$ http://node1/$1 [P,]
