Hello

In a 1:1 multilingual umbraco 8 site with 3 variants, the ideal goal for my 404 not found page is:

• www.example.com/this/is/not/a/page = English content message
• www.example.com/chinese/this/is/not/a/page = Chinese content message
• www.example.com/japanse/this/is/not/a/page = Japanese content message

(i.e. the first segment in the bad url can still be used to determine language context.)

I have defined a “IContentLastChanceFinder” content finder as per https://our.umbraco.com/documentation/reference/routing/request-pipeline/IContentFinder

This almost works well, but the trouble is my error configuration means the umbraco 404 response is trumped by the IIS level settings, and triggers a second 404 url by which time the original language context has been lost

<httpErrors existingResponse="Replace" errorMode="Custom">
  <remove statusCode="404" />
  <remove statusCode="500" />
  <error statusCode="404" path="/404contentfinder" responseMode="ExecuteURL" />
  <error statusCode="500" path="/ServerError.aspx" responseMode="ExecuteURL" />
</httpErrors>

The 500 rule is so the YSODs are replaced with a ‘friendly message’. I actually only want the httpErrors config to Replace 500, it would be great if I could “pass through” the 404 from Umbraco but alas the MS team don’t allow it to be set per status code ☹

Anyone have any working solutions?

Thanks heaps

Andrew
