ASP.NET page load twice when using url rewriting

Question

I have an asp.net page with url rewriting rule. The rule shows below:

 <rule name="DiscoverCategorySEO">
      <match url="^Discover/([0-9]+)/"/>
      <conditions>
        <add input="{URL}" negate="true" pattern="\.axd$"/>
      </conditions>
      <action type="Rewrite" url="News/Discover.aspx?Section={R:1}" redirectType="Permanent" appendQueryString="false"/>
</rule>

I put a break point in the Page_Load method for debugging. Then I found when I visit ' http://[domain]/Discover/1/ '. The discover page will load twice. However, if I put ' http://[domain]/News/Discover.aspx?Section=1 ", the break point will only be hit once.

Does anyone know how can I keep url rewriting rule and meanwhile load page only once?

<rule name="DiscoverCategorySEO"  enabled="true" stopProcessing="true">
    <match url="^Discover/([0-9]+)/"/>
          <conditions logicalGrouping="MatchAll">
            <add input="{URL}" negate="true" pattern="\.axd$"/>
            <add input="{PATH_INFO}"  pattern="^Discover/([0-9]+)/"  />
          </conditions>
          <action type="Rewrite" url="News/Discover.aspx?Section={R:1}" redirectType="Permanent" appendQueryString="false"/>
</rule>
