It depends where you're working.

In local? Windows or Linux? on a server?

I have linux and i am using 1 and 1(its a host). I have read in the webpage of 1 and 1 that i can't modify the httpd.conf file but it says that the command that i put in the htacces can work for all the webspace.

You have to enable mod_rewrite...

you need admin password to do this and to modify httpd.conf.

But my host says that i can't modify httpd.conf . Is there any command to enable mod_rewrite with htaccess?. My host says that i can do all in the htaccess file.

My host say this in a faq page:

You cannot modify the "httpd.conf" file of Apache Webserver in our Shared
hosting and Managed Server packages.

But you can adjust the Apache webserver properties to your needs by editing a
control file. You can list various commands in this file enabling you to control
access to a directory, to have custom error pages, to list the content of
directories, etc.

The control file ".htaccess" can be placed in various directories of your site.
Please note that commands in a .htaccess file effect ALL subdirectories as well!

If you want the changes to be applied to your entire webspace all you need to do is
place one .htaccess files containing the configuration into the maindirectory of
your space (/.)

The webpaage whre i founded that: http://faq.1and1.com/scripting_languages_supported/configuring_apache_server_using_htaccess/4.html
