Header Inserts

I am experiencing a somewhat odd situation. I created an HTTP profile and setup a name value pair in the Request Header Insert (SSL_ENV:On). When I debug in Fiddler to see if the header is inserted, I don't see anything which is really strange. So I went the iRule route and tried to test if the header was set and if it wasn't set it to On:

 

 

when HTTP_REQUEST {

 

set myhost [HTTP::host]

 

set myuri [HTTP::uri]

 

if { ![HTTP::header "SSL_ENV"] equals "On" } {

 

HTTP::header insert SSL_ENV On

 

log local0. "HEADER HTTPVS: [HTTP::header "SSL_ENV"]"

 

} else {

 

if { $myuri starts_with "/API" } {

 

log local0. "URL: $myuri going to non_ssl pool"

 

pool pool_one_80

 

} else {

 

HTTP::redirect "https://$myhost$myuri"

 

}

 

}

 

}

 

 

It throws a strange error on the ![HTTP::header

 

 

[undefined procedure: !HTTP::header] [!HTTP::header "SSL_ON"]

 

 

I thought inserting a header would be really straight forward and easy, but somehow I am missing something. Thoughts?

 

 

BTW: I created the same rule in SSL and HTTP to check if the header didn't exist and then create it. Still no dice.
