Multiple sites with the same URL

To create my website, I decided to use Visual Studio 2010. So, I have factories in which the Internet surfer can go there in two different ways. One way is to select a geographic name from the map that will put it in an aspx file at a specific location in my directory tree. The second way is to find the factory on the product page. In the second case, I use the “sitemap” in my code with the corresponding entries in my web.config file;

<siteMap defaultProvider="XmlSiteMapProvider" enabled="true">
        <providers>
            <add name="XmlSiteMapProvider" description="Default SiteMap provider" type="System.Web.XmlSiteMapProvider" siteMapFile="Web.sitemap" securityTrimmingEnabled="true"/>
            <add name="ProductsSiteMapProvider" description="Products SiteMap provider" type="System.Web.XmlSiteMapProvider" siteMapFile="Products.sitemap" securityTrimmingEnabled="true"/>
        </providers>

In my products.sitemap Im files I write the following entries:

<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/pages/products.aspx" title="Products" description="Greek Olive Products">
    <siteMapNode url="~/pages/products/oevoo/oevoo.aspx" title="Organic Extra Virgin Olive Oil" description="Find the Cultivation areas for this commodity" >
        <siteMapNode url="~/pages/products/oevoo/agioideka.aspx" title="Flathiakes" description="Cultivation Area Flathiakes, Herakleion Crete" />
        <siteMapNode url="~/pages/products/oevoo/handrinos.aspx" title="Handrinos" description="Cultivation Area Handrinos, village mountainous Messinia south-west Peloponnese " />
</siteMapNode>
    <siteMapNode url="~/pages/products/evoo/evoo.aspx" title="Extra Virgin Olive Oil" description="Find the Cultivation areas for this commodity" >
        <siteMapNode url="~/pages/districts/areas/agioideka.aspx" title="Flathiakes" description="Cultivation Area Flathiakes, Herakleion Crete" />
        <siteMapNode url="~/pages/districts/areas/acova.aspx" title="Acova" description="Standardization factory in Argolida east Peloponnese" />
        <siteMapNode url="~/pages/districts/areas/trikorfo.aspx" title="Trikorfo" description="Cultivation Area Trikorfo, mountainous area in south Peloponnese" />
        <siteMapNode url="~/pages/districts/areas/handrinos.aspx" title="Handrinos" description="Cultivation Area Handrinos, village mountainous Messinia south-west Peloponnese " />
    </siteMapNode>
    <siteMapNode url="~/pages/products/voo/voo.aspx" title="Virgin Olive Oil" description="Find the Cultivation areas for this commodity" >
  <siteMapNode url="~/pages/districts/areas/acova.aspx" title="Acova" description="Standardization factory in Argolida east Peloponnese" />
  <siteMapNode url="~/pages/districts/areas/trikorfo.aspx" title="Trikorfo" description="Cultivation Area Trikorfo, mountainous Messinia south Peloponnese" />
    </siteMapNode>
    <siteMapNode url="~/pages/products/to/to.aspx" title="Greek Table Olives" description="Find the Cultivation areas for this commodity" >
        <siteMapNode url="~/pages/districts/areas/trikorfo.aspx" title="Trikorfo" description="Cultivation Area Trikorfo, mountainous Messinia south Peloponnese" />

    </siteMapNode> 
</siteMapNode> 

Finally, when I try to run (locally) my website, it gives me the following error:

URL '/WebSite2/pages/districts/areas/acova.aspx'. XmlSiteMapProvider , Sitemap URL-.
