Applying lowercase iRule to HTTPS virtual server?

Ok, looks like I have a working solution now.

Thanks Stanislas - it's basically your rule blended into with my existing redirection rule.

So the lowercasing happens as planned, but also every HTTP/HTTPS/WWW/non-WWW combination still gets detected and 301 redirected too.

Just tested all 10 possible combinations for a page and all good so far.

1. mysitename.com/page (without HTTP/HTTPS/WWW) --> 301 redirect --> https://www.mysitename.com/page
2. mysitename.com/PAGE (without HTTP/HTTPS/WWW) --> 301 redirect --> https://www.mysitename.com/page
3. http://mysitename.com/page --> 301 redirect --> https://www.mysitename.com/page
4. http://mysitename.com/PAGE --> 301 redirect --> https://www.mysitename.com/page
5. http://www.mysitename.com/page --> 301 redirect --> https://www.mysitename.com/page
6. http://www.mysitename.com/PAGE --> 301 redirect --> https://www.mysitename.com/page
7. https://mysitename.com/page --> 301 redirect --> https://www.mysitename.com/page
8. https://mysitename.com/PAGE --> 301 redirect --> https://www.mysitename.com/page
9. https://www.mysitename.com/page --> HTTP/200 --> https://www.mysitename.com/page
10. https://www.mysitename.com/PAGE --> 301 redirect --> https://www.mysitename.com/page

Working iRule 1

when HTTP_REQUEST {
   if {[string tolower [HTTP::host]] starts_with "www.mysitename.com" && [string match {*[A-Z]*} [HTTP::uri]]}{
      HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::uri]]"
   } elseif
   {[string tolower [HTTP::host]] starts_with "mysitename.com" && [string match {*[A-Z]*} [HTTP::uri]]}{
      HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::uri]]"
   } elseif
    {[string tolower [HTTP::host]] starts_with "mysitename.com" } {
     HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::uri]]"
   }
}

I'm going to continue to test, but looks good so far.

If anyone can see any ways that I can optimize this rule and trim some fat off it, please let me know.

Thanks for everyone's input on this post... much appreciated.
