Question

Is it possible to put in exceptions to the above code? Like this on below, I know this example doesnt work but I think you get the idea of what I want. If address is "~/products/Item100" then go to item100.aspx, in all other cases "~/products.aspx?category=$1"

  <rewriter>
    <rewrite url="~/products/Item100" to="~/Item100.aspx" />
    <rewrite url="~/products/(.+)" to="~/products.aspx?category=$1" />
