Hi Mr Sysadmin,

 

 

I think the problem might be that you're rewriting the URI to nothing. Can you change your rewrites to:

 

 

HTTP::path [string map -nocase {/nodeX "/"} [HTTP::path]]

 

 

Also, if you want another option that supports pinning the request to the server for the duration of the session, you can try this Codeshare example:
