URL redirection by checking parameter

Question

I have URL like www.mysite.com/?cmd=login&param=1

I would like to redirect to another link if &param=1 parameter is not present

<rule>
<condition type="parameter" name="param" operator="notequal"/>
<from>^/(.*)</from>
<to type="redirect>www.mysite.com/$1</to>
</rule>

Could someone help me out if this is the correct way
