url-rewriting

Hi Everyone

I am working on a project where I have a search results page. I have rewritten the url.

My url:

www.xyz.com/city/area/search/category/cs-tCbQIY8hMYQ-TT-3d

Now here if remove the last part from the url (after the /) i.e.
www.xyz.com/city/area/search/category I get an error 404 page not found.

How can I avoid this error by redirecting the user to an existing page.

I know this is possible

<customErrors mode="RemoteOnly" defaultRedirect="~/Error">
   <error statusCode="500" redirect="~/Error" />
   <error statusCode="404" redirect="~/NotFound" />
</customErrors>

But is it possible to redirect in all situations

www.xyz.com/city/area/search/category/cs-tCbQIY8hMYQ-TT-3d
www.xyz.com/city/area/search/category/
www.xyz.com/city/area/search/
www.xyz.com/city/area/
www.xyz.com/city/

Do I have to create page for each possibility?

Please guide.

Thanks

What I have tried:

The rule I am using in webconfig

<rule name="city and category">
<match url="^([_0-9a-z-]+)/([_0-9a-z-]+)/([_0-9a-z-]+)/([_0-9a-z-]+)/([_0-9a-z-]+)$" />
<action type="Rewrite" url="/searchresults.aspx?city={R:1}&area={R:2}&type={R:3}&query={R:4}&cc={R:5}" redirecttype="Permanent" />
</rule>
