Url rewrite 302 redirecting trailing slash

Vote:
 

The Urlrewriter is producing a 302 redirect in a very specific scenario:

http://www.baigent.com/Portfolio is redirected to http://www.baigent.com/Portfolio/ in this way.

for SEO reasons we obviously would prefer this to be a permanent redirect... after initial research into this I'm not entirely sure if this is the the UrlRewrite's doing or if IIS is to blame.

Note the rewrite section is pretty much standard:

  <urlRewrite defaultProvider="EPiServerFriendlyUrlRewriteProvider">
    <providers>
      <add name="EPiServerFriendlyUrlRewriteProvider" type="EPiServer.Web.FriendlyUrlRewriteProvider,EPiServer" />
      <add description="EPiServer identity URL rewriter" name="EPiServerIdentityUrlRewriteProvider" type="EPiServer.Web.IdentityUrlRewriteProvider,EPiServer" />
      <add description="EPiServer bypass URL rewriter" name="EPiServerNullUrlRewriteProvider" type="EPiServer.Web.NullUrlRewriteProvider,EPiServer" />
    </providers>
  </urlRewrite>
 
Anyone encountered anything similar?

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
