How to set mod_rewrite module?

I am trying to set up the rewrite module. I want to redirect the quest to another port.

at the very beginning, I added
RewriteEngine on
RewriteCond %{HTTP_HOST} ^....URL_NAME....*
RewriteRule ^/(.*)$ http://localhost:3500/$1 [P] [L]

It complaints like below
"Invalid command 'RewriteEngine', perhaps mis-spelled or defined by a module not included in the server configuration"

Then I added
LoadModule rewrite_module modules/mod_rewrite.so

It complaints again like
"Invalid command 'RewriteEngine', perhaps mis-spelled or defined by a module not included in the server configuration"

does anyone know the problem?

Thanks.

So which file and where exactly? Is it within a <Location> block or <Directory> block or something?

What configure option did you give when compiling Apache?

Did you compile mod_so into Apache??
Check if you did by typing: httpd -l
and make sure that mod_so.c is displayed.

Otherwise, re-build Apache with mod_so or just compile mod_rewrite statically with
Apache.

Hope this helps.
