irule based redirection issue

Currently client sends URL request mylocalnet.us which is redirected to https with www code which is code 301. Once redirected to https://www.mylocalnet.us it is offloaded on ltm and request is sent to Web Server. Web server responds 302 https://www.mylocalnet.us/pages/variationroot.aspx which is used for language detection. If FR detected, server replies https://www.mylocalnet.us/fr/pages/default.aspx or with /en per language support. Actual purpose is to avoid multiple redirections on server side and perform these operations on ltm to expedite response time. Sharing with you unmodified code.

    only look at text data
        if { [HTTP::header Content-Type] contains "text" } {
  create a STREAM expression to replace any http:// with https:// for CDN
STREAM::expression {@http://bt.mylocal.ae@https://bt.mylocal.ae@ @www.mylocalnet.us@ @http://www.mylocalnet.us@https://www.mylocalnet.us@}
