Trailing slashes in website

Trailing slashes in your website.
We got some SEO requirements for a website that
1. All the links in website either should have a trailing slash (preferred) or not.
2. Further if user enters www.site.com it should automatically redirect to www.site.com/ . Our site is a commerce site and using DefaultHierarchialRouter for commerce routing.

For the first requirement solution is very simple. In some initialization module we can force trailing slash for the website using EPiServer.Web.Routing.ContentRoute.UseTrailingSlash = true;

For the 2nd requirement in 7.5 multiple suggestion came by Quan and Johan. You can find those details under thread http://world.episerver.com/Modules/Forum/Pages/Thread.aspx?id=113080. But we preferred to install IIS rewrite module to solve this issue, that can be downloaded from http://www.microsoft.com/en-us/download/details.aspx?id=5747 and can be setup http://thatsit.com.au/seo/tutorials/how-to-fix-canonical-issues-involving-the-trailing-slash 
We requires some extra rules to avoid trailing slash for online center, images, and other static contents. You can find a general rule set for an episerver site as following
<rule name="AddTrailingSlashRule1" stopProcessing="true">
<match url="(.*[^/])$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{URL}" pattern="/bundles/" negate="true" />
<add input="{URL}" pattern="/cm/UI/" negate="true" />
<add input="{URL}" pattern="/App_Themes/" negate="true" />
<add input="{URL}" pattern="/util/" negate="true" />
<add input="{URL}" pattern="/SearchAction" negate="true" />
<add input="{URL}" pattern="/Index" negate="true" />
<add input="{URL}" pattern="/globalassets/" negate="true" />
</conditions>
<action type="Redirect" url="{R:1}/" />
</rule>
