Web.Config URL Rewrite Question

[Krus1972]

I am using the following rule in my web.config file and I am having a few issues. I hope someone can help:

     <rewrite>
       <rules>
          <rule name="Shopping">
             <match url="^([_0-9a-z-]+)" />
             <action type="Rewrite" url="?thesearch={R:1}" />
          </rule>
          <rule name="Reviews">
             <match url="^([_0-9a-z-]+)/reviews" />
             <action type="Rewrite" url="/Reviews_Desktop.asp?thesearch={R:1}" />
          </rule>
       </rules>
    </rewrite>

1.) Does anyone know how I can exclude certain keywords from the "Shopping" Rule? For example I would like to exclude "popularkeywords" and "auctions" from the "Shopping" rewrite rule. If a URL such as http://mydomain.com/popularkeywords or http://mydomain.com/auctiions gets used, the server will NOT rewrite it. Is it possible to exclude certain keywords in this fashion?


2.) The "Reviews" rule will not work because the "Shopping" rule kicks in before hand. Is there anyway to have the server ignore the "Shopping" rule when there is a /reviews/ at the end of the URL as shown in the "Reviews" rule?

I would appreciate any help.

Thanks.
