HTTPS VIP for HTTP Website

If you have the option of modifying the application, you could make the absolute URLs relative. This avoids the need to do any payload rewriting and will work for HTTP or HTTPS. If not, I'd probably skip proxypass and just use a stream profile and iRule for this.

Here's one recent example:

http://devcentral.f5.com/Community/GroupDetails/tabid/1082223/aff/5/afv/topic/aft/1179185/afc/1250734/Default.aspx

when HTTP_REQUEST {

    Save the requested host value
   set host [string tolower [HTTP::host]]

    Disable the stream filter by default
   STREAM::disable
}
when HTTP_RESPONSE {

    Check if response type is text and host isn't null
   if {[HTTP::header value Content-Type] contains "text" and $host ne ""}{

       Replace http://$host with https://$host
      STREAM::expression "@http://$host@https://$host@"

       Enable the stream filter for this response only
      STREAM::enable

      if { [HTTP::is_redirect] } {
         HTTP::respond 302 Location [string map -nocase "http://$host https://$host" [HTTP::header Location]]
   }
}
