Thanks for the feedback everyone.
The issue I'm seeing is since xyz.com is internal domain and complete URL of the app is abc.xyz.com/HTTP::uri. so some users prefer to type only and the app team wants that whenever a user types it should get redirected to http://abc.xyz.com. because otherwise the application will break.
Now, when i set redirect like this:
if { [string tolower [HTTP::host]] equals "abc" {
HTTP::redirect "http://abc.xyz.com[HTTP::uri]" }
Some URL's work while some don't
for example: gets redirected to http://abc.xyz.com/HTTP::uri
but gets redirected to http//abc/ and not http://abc.xyz.com
Any suggestion, could it be server issue?
Thanks in advance.
