Irule Redirection not working Properly

Can you explain the irule

the author stores url in data group (spaces_sharepoint_redirect_class) instead of hard-coding it in the irule.

I was wondering if I can have a simple irule wherein i put any HTTP_Request for hiringmanagement.fmr.com com should go to http://fidelity.taleo.net/smartorg/saml20authnrequestservlet.jss?redirectionURI=https%3A%2F%2Ffidelity.taleo.net%2Fsmartorg%2Fsmartorg%2Fcommon%2Ftoc.jsf%3Flang%3Den.

e.g.

[root@ve11c:Active:In Sync] config  tmsh list ltm rule qux
ltm rule qux {
    when HTTP_REQUEST {
  if { [HTTP::host] eq "hiringmanagement.fmr.com" and [HTTP::uri] eq "/" } {
    HTTP::redirect "http://fidelity.taleo.net/smartorg/saml20authnrequestservlet.jss?redirectionURI=https%3A%2F%2Ffidelity.taleo.net%2Fsmartorg%2Fsmartorg%2Fcommon%2Ftoc.jsf%3Flang%3Den"
  }
}
}

[root@ve11c:Active:In Sync] config  curl -I http://hiringmanagement.fmr.com
HTTP/1.0 302 Found
Location: http://fidelity.taleo.net/smartorg/saml20authnrequestservlet.jss?redirectionURI=https%3A%2F%2Ffidelity.taleo.net%2Fsmartorg%2Fsmartorg%2Fcommon%2Ftoc.jsf%3Flang%3Den
