sendRedirect and 404 Page not found

I was wondering if there is a way to first determine if the page exists in a response.sendRedirect(strURL);

first. If the page does not exist then display another page stating why the page does not exist.

Example. Page not found, please try again when processing has completed. I tried using this but it does not work:

try {

response.sendRedirect(strURL);

}

catch(IOException ex) {

response.sendRedirect(strURL2);

}

In this situtaion I am first trying to redirect to a page that may not be ready there yet on the C:\drive.

Thanks
