redirect rewirte option in http profile causing looping

I ran into this on a project:

• http and https Virtual Servers
• http to https redirect irule
• https offload to http pool
• http profile with Redirect Rewrite: All

• Page would not load correctly (html would load but no CSS or images)
• Fiddler revealed that the application servers were redirecting all content requests to the base uri with a single-sign-on logoff parameter appended...and then redirecting the redirect with a duplicate parameter appended...and then again...
• It looped like this until the redirect had 10+ duplicate parameters and it finally gave up, but never returned the real content.

• Finally determined that Redirect Rewrite was rewriting the Referer header to "https://sub.domain.com/path/", which the application (on http) was rejecting/redirecting.
• Used this iRule to rewrite incoming Referer header to "http://sub.domain.com/path/"

    when HTTP_REQUEST {
    set referer [HTTP::header "Referer"]
    if { $referer starts_with "https://" } {
        set httpReferer "http://[string range $referer 8 end]"
        HTTP::header replace "Referer" $httpReferer
    }
}
