Hi Sunil,
The following script named "redirect.tcl"
ns_set put [ns_conn outputheaders] myHeader foo
ns_returnredirect /
returns the following to the browser
Connection:keep-alive
Content-Length:307
Content-Type:text/html; charset=utf-8
Date:Fri, 21 Apr 2017 17:07:45 GMT
Location:/
myHeader:foo
Server:NaviServer/4.99.16d4
... so, the extra header is includes, everything works as expected. This is with NaviServer 4.99.16d4.
What exact server are you using?
