I would like to change my header when I went to another page, but I am not able to put my html file. I searched before coming here to ask, I tried this way, but just remove the header, I can not add another.
ultimo/default/layout/local.xml
<checkout_cart_index><!-- Custom static blocks -->
<reference name="checkout.cart">
<remove name="header" />
<block type="page/html_header" name="header" template="page/html/header_checkout.phtml"/>
<block type="cms/block" name="block_cart_below_table">
<action method="setBlockId"><block_id>block_cart_below_table</block_id></action>
</block>
<block type="cms/block" name="block_cart_below_totals">
<action method="setBlockId"><block_id>block_cart_below_totals</block_id></action>
</block>
</reference>
</checkout_cart_index>
