Well this is weird, we have a Sitecore 9.1 multisite, and when someone tries to access https://www.abc.com/www.cc.com/ it is redirecting to 200 status code but with a server error message but if I remove www. -- .com and keep only https://www.abc.com/cc/ it gives custom error page with page not found error message. I tried to find any solutions for this in blogs but could not find any. What could be the reason for this?

  • The request with /www.cc.com (without trailing slash) is handled at the IIS level and IIS considers it as a file in the file system and it returns the IIS error if not present. If you add trailing slash, Sitecore will return the error. What kind of server error are you seeing when you browse path with dots? Mar 10, 2022 at 19:58
  • There is a custom error HTML page which is shown to the user if user tries to access abc.com/www.cc.com and if he tries to browse only abc.com/cc , user is shown a 500 error page which is served from ErrorHandler code but this code never gets executed when I browse abc.com/www.cc.com

    Does this answer your question? How do you setup a 404 and 500 error page for missing files and media items? This is a very helpful post and discussion that explains why it happens and how to solve it.

Please write a custom url handler, there you can handle the paramter you are receiving and redirect to 404 as and when required.
