Url rewritting not worked properly

Url rewritting not worked properly

I have two rules as follows..
<rule source="Admission/Undergraduate/Selection-Criteria"
destination="HomePageContents/Selection_Criteria99.aspx" />
<rule
source="Admission/Undergraduate/Selection-Criteria/Application-Requirement"
destination="HomePageContents/Application_Requirement103.aspx" />
but when I want to navigate to
'Admission/Undergraduate/Selection-Criteria/Application-Requirement ' I
got an error
'Requested URL:
/TestDomain/HomePageContents/Selection_Criteria99.aspx/Application-Requirement'
Please resolve this.
