    Patrik, good one. You have typo. It should be:

    if { [PROFILE::exists clientssl] == 1 } {
    set protocol "https"
} else {
    set protocol "http"
}

    I'm doing this on CLIENT_ACCEPTED. The method with CLIENTSSL_HANDSHAKE will not work because BIG-IP refuse to load it on VS without SSL profile.

Chris,

I think URI::protocol will only parse the protocol from a full URL that already has the protocol listed. I could imagine it being useful for parsing fully qualified URLs in requests through a web proxy. However, if the client didn't include the protocol in the URI, I expect URI::protocol wouldn't return anything: 


when RULE_INIT {
log local0. "\[URI::protocol /path/to/file.ext\]: [URI::protocol /path/to/file.ext]"
log local0. "\[URI::protocol https://www.example.com/path/to/file.ext\]: [URI::protocol https://www.example.com/path/to/file.ext]"
}
 : [URI::protocol /path/to/file.ext]:
 : [URI::protocol https://www.example.com/path/to/file.ext]: https
