mod rewrite not working in LiteSpeed

[Ness3k]

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?

Thanks.

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.

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