HTTP to HTTPS redirect

Try removing the brackets around the HTTP::redirect command

when HTTP_REQUEST {
 if { [HTTP::host] eq "test.abc.com"} {
  HTTP::redirect "https://test.abc.com/"
 }
}

The square brackets evaluate the command inside the brackets and then place the result where the brackets are. You want to execute the command so you'll want to not include the brackets.

*** Update ***

I forgot to mention (as rapmaster_c did below) that you'll want to be checking based on HTTP::host and not HTTP::uri. I've updated the example above.
