Nimbostratushow do you check for a null http referer
I want to check for a blank http referer for an IRULE
([HTTP::header "Referer"] equals $null)
is there some type of variable or way to check for this?
Would I have to use the length function for the http::referrer?

I think [HTTP::header $header_name] will return a null string even if the header doesn't exist, so you could combine that with a check to see if the header exists:
if {[HTTP::header exists Referer] && [HTTP::header Referer] eq ""}{
Or if you just want to check that it's not null you could use:
if {[HTTP::header Referer] ne ""}{
