This Package action will Add a new url rewriting rule to the UrlRewriting.config file. The undo option makes sure that the rewriting rule can be removed again at uninstall.
Alias: AddUrlRewriteRule
<Action runat="install"
undo="true/false"
alias="AddUrlRewriteRule">
<add name="CWS_emaiAFriendID"
virtualUrl="^~/email-a-friend/(.[0-9]*).aspx"
rewriteUrlParameter="ExcludeFromClientQueryString"
destinationUrl="~/email-a-friend.aspx?nodeID=$1"
ignoreCase="true" />
</Action>
One thing worth noting is that by default the re-directs are 302 re-directs, if you want to do 301 re-directs you need to add the following:
redirectMode="Permanent"
