+===== Implemente internal redirect on LiteSpeed through header =====
 To get this to work on LiteSpeed, just use a simple header "X-LiteSpeed-Location" in your php script.
-==== Set header "Location" in your php script ====
+==== Method 1: Set header "Location" in your php script ====
 Set "**Location**" header pointing to a URL without ''<nowiki>http://domain</nowiki>'', just the URL without the hostname part. Do not set a "**Status**" header in response. Make sure no "Status" header is returned. PHP always adds "**Status**" header automatically when a "**Location**" header was set.

+For example, put a line like below to the php script:
   header('X-LiteSpeed-Location: /path/to/file_to_be_redirected');

-That's it folks. LiteSpeed will take over the the rest, perform an internal redirect, and send back the file with sendfile() support if the url points to a static file.
