Applying lowercase iRule to HTTPS virtual server?

Hi 1000blocks,

you may take a look to the two iRules below. Both iRules are using a very fast code path to identify the "good" requests (should be >90% of the total request).

In addition both iRules are not [string tolower] the entire [HTTP::uri] string, since this approach may break certain applications. Both iRules will therefor [string tolower] only the [HTTP::host] and/or [HTTP::path] information, while keeping possible [HTTP::query] information in the original case.

iRule1: If is the only sitename served by the virtual server.

when HTTP_REQUEST {
    if { [string tolower "[HTTP::host][HTTP::path]"] equals "www.mysitename.com[HTTP::path]" } then { 
         Allow the request to pass. Should be >90% of the requests. 
        return
    }
     Wrong host or mixed case URL requested. 
    if { [HTTP::query] ne "" } then {
        HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::path]]?[HTTP::query]"
    } else {
        HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::path]]"
    }
}

iRule2: If multiple sitenames are served by the virtual server.

when HTTP_REQUEST {
    switch -glob -- [string tolower [HTTP::host]] {
        "www.mysitename.com" {
            if { [string tolower [HTTP::path]] equals [HTTP::path] } then {
                 Allow the request to pass... 
            } else {
                if { [HTTP::query] ne "" } then {
                    HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::path]]?[HTTP::query]"
                } else {
                    HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::path]]"
                }
            }
        }
        "*mysitename.com*" {
            if { [HTTP::query] ne "" } then {
                HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::path]]?[HTTP::query]"
            } else {
                HTTP::respond 301 noserver Location "https://www.mysitename.com[string tolower [HTTP::path]]"
            }
        }
        "www.mysitename2.com" {
            if { [string tolower [HTTP::path]] equals [HTTP::path] } then {
                 Allow the request to pass... 
            } else {
                if { [HTTP::query] ne "" } then {
                    HTTP::respond 301 noserver Location "https://www.mysitename2.com[string tolower [HTTP::path]]?[HTTP::query]"
                } else {
                    HTTP::respond 301 noserver Location "https://www.mysitename2.com[string tolower [HTTP::path]]"
                }
            }
        }
        "*mysitename2.com*" {
            if { [HTTP::query] ne "" } then {
                HTTP::respond 301 noserver Location "https://www.mysitename2.com[string tolower [HTTP::path]]?[HTTP::query]"
            } else {
                HTTP::respond 301 noserver Location "https://www.mysitename2.com[string tolower [HTTP::path]]"
            }
        }
        default {
             Further/Unknown HOST-names...
        }
    }
}
