Found out about this today. Did you get anywhere with the investigation how to change this to 301?

If you take a look at the method ConvertToInternalInternal inside the FriendlyUrlRewriteProvider

if (!url.Path.EndsWith("/"))
		{
			url.Path += "/";
			HttpContext.Current.Response.Redirect(url.Path + url.Query + url.Fragment);
		}

    Guess you can make your own and override that redirect

Thanx Anders. It worked for Episerver 5 version. In 6R2 FriendlyUrlRewriteProvider is changed so I cannot find suitable location to check and add 301. If anybody has a clue, it would help.

Hi, I have the same problem. Status code in case of missing trailing slash instead of 302 should be 301. Found place where trailing slash is analysed:

EPiServer.Web.FriendlyUrlRewriteProvider, ConvertToInternalInternal method

But I could not figure out the correct place to change status code. Can you please give me a clue.

Thanks in advance,

Artem

Hi, same problem here. How did you manage to solve this problem? 

TIA.
