Sharepoint SEO - How to lowercase urls with rewrite rules?

[firstconversion]

We have a  borked website running on sharepoint IIS .net that has been at the mercy of many bad developers

We have rewrite rules with an ini file for 301s etc. We are struggling to find out or figure out how to lowercase them

The lowercase functionality may be native within sharepoint somewhere

Any help appreciated! Sorry its so vague

Some update from the dev

We’re using IIS6 and Ionic Isapi filter

There are some instruction I found on a forum that do the lowercase redirect

Finally, downcase as necessary.  If there are any

uppercase characters in the URL, apply this rule.

RewriteCond %{url}   [A-Z]+

RedirectRule ^(.*)$  #L$1#E     [R=301]

Will feedback if it works

a lot of rewrites use similar rules. not sure if this will help but:
http://www.isapirewrite.com/docs/

mentions  using "CL" (Case Lower)

Not 100% sure they will help but thought I would pass them on in case they did.

Hi Stephen,

I'm going back through the older unanswered questions. Did you ever get this figured out? Can you share a solution with us for the archives if you did?

Here's how to achieve what you need through an IIS URL Rewrite:

<rewrite><rules><rule name="ForceLowercase" stopprocessing="false"><match url=".[A-Z]." ignorecase="false"><action type="Redirect" redirecttype="Permanent" url="{ToLower:{R:0}}"></action></match></rule></rules></rewrite>

Translation: If the URL contains any uppercase letters, convert it to all lowercase, then continue processing other rules.  (You can name the rule whatever you want.)

These rewrite rules are stored either in the ApplicationHost.config file or in Web.config files. More info and step-by step instructions: creating IIS URL Rewrites.

Note: Compared to the [ISAPI_Rewrite] filters (httpd.ini), I've found that the IIS URL Rewrite (web.config) rules seem to match the syntax of Apache more often. As a result, it's easier to find RegEx expressions already written for what you need. It also helps to focus on debugging the actual code versus some strange IIS exception. Good luck!
