Hello! I have a page with several webscripts on it.

Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<page> 
   <id>scans</id>
   <title>Сканы</title>
   <template-instance>scans</template-instance>
   <authentication>none</authentication>
   <components>
        <component>
            <region-id>center</region-id>
            <url>/scans/upload</url>
        </component>
        <component>
            <region-id>listbox</region-id>
            <url>/scans/list</url>
        </component>
    </components>
</page>
How can i pass page "GET" args (example ./scans?tag=mech)
only to second web script?
